Filet Crochet: A Complete Beginner’s Guide with Free Pattern

If you’ve ever admired those delicate, lace-like pieces with beautiful picture designs made from simple open and filled squares, you’ve already fallen in love with filet crochet — you just might not have known what to call it. This centuries-old technique creates stunning fabric from nothing more than chains and double crochet stitches, arranged in a grid to form images, text, and decorative motifs. Despite looking incredibly intricate, filet crochet is one of the most approachable forms of lace-making for beginners.

In this complete guide, you’ll learn everything you need to get started — from understanding the basic structure of filet crochet grids, to reading charts, to working your very first project using a free beginner pattern included at the end. Whether you’re brand new to crochet or an experienced crocheter looking to try something new, this tutorial will walk you through every step with clarity and confidence.

What Is Filet Crochet?

Filet crochet is a type of crochet worked on a grid made up of two types of spaces: open spaces (called “spaces” or “meshes”) and filled spaces (called “blocks”). By combining these two elements in specific arrangements, you can create pictures, patterns, and text that look almost woven or embroidered into the fabric.

The word “filet” comes from the French word for “net,” and that’s exactly what the open mesh resembles — a fine net with motifs filled in at strategic points. Traditionally, filet crochet was used to create household linens like curtain panels, tablecloths, dresser scarves, and edgings. Today it’s used for all of those plus wall hangings, pillow covers, bookmarks, framed art, and even fashion accessories.

What makes filet crochet so appealing to beginners is its simplicity at the stitch level. You only ever work two stitches: the chain stitch and the double crochet stitch (using US terminology throughout this guide). All the complexity comes from how those stitches are arranged, and that arrangement is guided by a chart — a grid of filled and empty squares — making the pattern easy to follow visually.

Tools and Materials You’ll Need

Before you sit down to start your first filet crochet project, gather the following supplies.

Thread or yarn: Traditional filet crochet uses cotton crochet thread, typically size 10, which creates fine, elegant fabric with excellent stitch definition. If you’re a true beginner and want to learn the structure more easily, you can start with a light-worsted weight cotton yarn, which works up larger and is much easier to see.

Crochet hook: Your hook size should match your thread or yarn. Size 10 crochet thread typically uses a steel hook in sizes 7 to 10 (roughly 1.5mm to 1.15mm). If you’re working with worsted weight cotton yarn, start with a 4.0mm or 4.5mm hook.

Scissors: A small, sharp pair works best for trimming thread ends cleanly.

Tapestry needle: You’ll use this to weave in your ends when the project is finished.

Stitch markers: Optional but helpful for marking the beginning of rows, especially when you’re learning.

Printed or digital chart: Filet crochet is worked from a chart. You’ll find the free beginner pattern chart at the end of this post.

Understanding the Grid: Spaces and Blocks

Everything in filet crochet comes back to the grid. Think of a piece of graph paper. Each square on that graph represents either a space (open mesh) or a block (filled mesh).

A space consists of: 1 double crochet, 2 chains, 1 double crochet. The two chains create the open “window” you see in the mesh, and the double crochets on either side form the vertical bars of the grid.

A block consists of: 4 double crochets worked consecutively. When a block sits next to another block, they share one of their vertical double crochets, so each additional block in a row adds 3 double crochets rather than 4.

When you look at a filet crochet chart, filled squares indicate blocks and empty squares indicate spaces. The picture forms because blocks catch the eye as solid areas against the open mesh background, or vice versa — sometimes the motif is the open mesh against a filled background.

How to Read a Filet Crochet Chart

Charts might look intimidating at first, but they’re actually quite intuitive once you understand the logic.

Each row of squares on the chart represents one row of crochet. You work from the bottom of the chart upward. Right-side rows are typically worked from right to left on the chart, and wrong-side rows are worked from left to right — which mirrors the physical motion of crocheting back and forth.

An open square means you work a space: double crochet, chain 2, double crochet. A filled square means you work a block: 4 double crochets (or 3 if it follows another block). That’s genuinely all the information you need to read any filet crochet chart in the world, regardless of its complexity.

Some charts include additional symbols for increases and decreases at the edges, which allow the fabric to grow or shrink in width to form shaped pieces. For your first project, however, you’ll work a simple rectangular piece where every row has the same number of squares, making it easy to follow.

How to Calculate Your Starting Chain

To begin a filet crochet piece, you need to work a foundation chain. Here’s the formula:

For each square in the width of your chart, you need 3 chains. Then you add 4 more chains at the end to account for the turning chain and the first space or block.

So if your chart is 10 squares wide: (10 × 3) + 4 = 34 chains.

If your pattern begins with a space in the bottom right corner (which is most common), your starting chain setup is: chain the required number, then work your first double crochet into the 8th chain from the hook. This creates your first open space. If your pattern begins with a block, you work the first double crochet into the 4th chain from the hook.

Don’t worry if this feels abstract right now — the free pattern below gives you the exact chain count and setup instructions.

Working Spaces and Blocks Row by Row

Once your foundation is established, you work each row by reading across your chart and creating the appropriate stitch combination for each square.

When you reach the end of a row, you turn your work and begin the next row. The turning chain for filet crochet is typically chain 5 (which counts as 1 double crochet plus a 2-chain space) if your row starts with a space, or chain 3 (which counts as 1 double crochet) if your row starts with a block.

This is one of the small technical details that trips beginners up. Here’s a simple approach: before you turn, look at the first square in the next row on your chart. If it’s open, chain 5 and turn. If it’s filled, chain 3 and turn.

As you work back across the row, remember that the turning chain serves as the first double crochet of that edge stitch. So when you finish the row, your last stitch will be worked into the top of the turning chain from the previous row.

Take it slowly at first. Work a row, set it down, look at what you’ve made, and compare it to the chart. This habit of checking your work against the chart after each row will save you a lot of frustration and help you develop a feel for how the chart translates into fabric.

Tips for Keeping Your Tension Consistent

One of the hallmarks of beautiful filet crochet is an even, consistent tension throughout the piece. Here are some practical tips to help you achieve that.

Hold your thread or yarn consistently throughout the project. Many crocheters wrap the working thread around their index finger once or twice to maintain gentle tension as it feeds through their fingers. Find a method that feels comfortable and stick with it.

Work your chains at the same tightness as your double crochets. Loose chains create floppy, irregular mesh; tight chains create distorted squares. If you tend to chain tightly, try going up one hook size just for your foundation chain.

Don’t pull your work too hard at the end of each row when you turn. The edge stitches of filet crochet tend to be where tension problems show up most visibly. Working the edge double crochets with a light, relaxed hand goes a long way.

Block your finished piece. Blocking is a finishing technique where you wet the piece, pin it to a flat surface in the correct dimensions, and let it dry. For cotton thread or yarn, blocking is transformative — it evens out stitches, opens up the mesh, and makes the motif pop with clarity. You’ll be amazed at the difference it makes.

Common Beginner Mistakes (and How to Avoid Them)

Accidentally skipping a chain space or working into the wrong stitch is the most common mistake in filet crochet, and it throws off your stitch count immediately. Count your squares at the end of every row and compare to the chart. If your count is off, it’s much easier to find and fix the error in the same row than to discover it three rows later.

Another common issue is confusing where to work your double crochets within a block. When working a block, you work 4 double crochets — or 3 if you’re adding a block next to an existing block — into the tops of the stitches, not into the chain spaces. When working a space, you work 1 double crochet, chain 2, then skip the 2 stitches below and work the next double crochet into the top of the next post stitch.

It also helps to think of the chart not as a picture to admire but as a set of instructions to execute one square at a time. Beginners sometimes get excited looking ahead at the chart and lose track of where they are. Use a ruler or sticky note to cover the rows above the one you’re working, revealing only your current row. This keeps you focused.

Free Beginner Filet Crochet Pattern: Simple Heart Bookmark

This free pattern creates an adorable heart bookmark worked in filet crochet. It’s small, quick to finish, and gives you practice with both spaces and blocks. The finished piece measures approximately 2.5 inches wide by 7 inches long using size 10 cotton thread and a 1.65mm steel hook, or approximately 4 inches wide by 11 inches long using worsted weight cotton yarn and a 4.0mm hook.

Materials:
A small amount of size 10 cotton crochet thread in any color, or light worsted weight cotton yarn. One steel hook size 7 (1.65mm) for thread, or a 4.0mm aluminum hook for yarn. Scissors and a tapestry needle.

Abbreviations (US terms):
ch = chain, dc = double crochet, sp = space (dc, ch2, dc), bl = block (4 dc or 3 dc when adjacent to another block), sk = skip, st = stitch, t-ch = turning chain.

Chart (read bottom to top, right-side rows right to left, wrong-side rows left to right):

Row 1 (bottom): [sp] [sp] [sp] [sp] [sp] — 5 spaces
Row 2: [sp] [bl] [sp] [bl] [sp] Row 3: [bl] [bl] [bl] [bl] [bl] Row 4: [bl] [bl] [bl] [bl] [bl] Row 5: [sp] [bl] [bl] [bl] [sp] Row 6: [sp] [sp] [bl] [sp] [sp] Row 7: [sp] [sp] [sp] [sp] [sp] Row 8: [sp] [sp] [sp] [sp] [sp] Row 9: [sp] [sp] [bl] [sp] [sp] Row 10: [sp] [bl] [bl] [bl] [sp] Row 11: [bl] [bl] [bl] [bl] [bl] Row 12: [bl] [bl] [bl] [bl] [bl] Row 13: [sp] [bl] [sp] [bl] [sp] Row 14: [sp] [sp] [sp] [sp] [sp]

Instructions:

Foundation chain: Chain 19.

Row 1 (right side): Work 1 dc into the 8th chain from hook (counts as first space), [ch 2, sk 2 ch, dc in next ch] 4 times — 5 spaces made. Chain 5, turn.

Row 2: Dc into first dc (completing the first space), ch 2, sk 2 ch sp, dc in next dc (second space complete), dc in ch-2 sp, dc in next dc (block made), ch 2, sk next dc, dc in next dc (space), dc in ch-2 sp, dc in next dc (block), ch 2, dc in 3rd ch of t-ch (final space). Chain 3, turn.

Continue in this manner, following the chart row by row. For right-side rows, begin with ch 5 if the row starts with a space, or ch 3 if it starts with a block. For each space, work dc, ch 2, dc. For each block, work 4 dc (or 3 dc when following another block).

Finishing: Fasten off and weave in ends with your tapestry needle. If desired, add a small tassel or ribbon loop at one end for a decorative touch. Block lightly by misting with water, pinning to shape, and allowing to dry completely.

Moving Forward: What to Make Next

Once you’ve completed the heart bookmark, you’ll have a solid foundation in the fundamentals of filet crochet. The skills you’ve practiced — reading charts, working spaces and blocks, managing turning chains, and maintaining an even tension — are everything you need to tackle more ambitious projects.

A natural next step would be a small square or rectangular motif, such as a coaster or a decorative patch, where you can practice a slightly more complex design like a butterfly, initial letter, or simple floral motif. From there, filet crochet curtain panels, table runners, and wall hangings become genuinely achievable.

The world of filet crochet charts is enormous. Once you understand how to read the grid, you can follow any filet chart you find — in books, in vintage pattern collections, or downloadable from designers online. Some crafters even create their own charts by converting images to pixel art using free online tools, then interpreting each pixel as a space or block.

You might also explore the beautiful tradition of monogram filet crochet, where alphabet charts allow you to work a person’s initials into a piece. This makes for deeply personal, handmade gifts — pillowcases, tote bag patches, framed pieces — that feel genuinely luxurious.

Final Thoughts

Filet crochet rewards patience. Your first few rows might feel slow and a little mechanical as you find your rhythm, look at your chart, count your squares, and check your work. That’s perfectly normal and exactly how it’s supposed to feel. Within a few rows, you’ll find yourself speeding up, developing a feel for the rhythm of spaces and blocks, and glancing at the chart only to confirm what your hands are already anticipating.

There’s also something deeply meditative about filet crochet — the repetitive motion, the gradual emergence of an image from nothing but thread and a hook, the quiet satisfaction of finishing a row and seeing the picture come a little more into focus. It connects you to generations of crafters going back centuries who made their tablecloths, christening gifts, and lace curtains stitch by careful stitch.

Start with your bookmark, be patient with yourself, and enjoy the process. The techniques you build here will open up an entire world of lace-making that is far more accessible than it looks — and far more rewarding than you might expect.

Happy crocheting.
