Filet Crochet Patterns

How filet crochet works

Filet crochet is the simplest technique in crochet to describe and one of the most impressive to look at. You work a grid of squares in trebles and chains: a filled square, called a block, and an empty square, called a space. The pattern is a chart where filled squares are shaded, and your job is to read it and follow. There are no unusual stitches, no fiddly manoeuvres and nothing to memorise — which is why filet is genuinely accessible to a confident beginner while producing work that looks like heirloom lace.

Reading a filet chart

Charts are read from the bottom up, right to left on right-side rows and left to right on wrong-side rows, unless the designer states otherwise. Each square is normally a treble plus two chains for a space, or three trebles for a block, with the sides of adjacent squares shared. Before you start a large piece, count the squares across the widest row of the chart and work out your foundation chain from that; getting this wrong at the beginning is the single most common filet mistake, and it does not become obvious until row twenty.

What to make

• Table runners and doilies: the classic use, in fine cotton with a small hook.
• Curtains and window panels: filet's open grid filters light beautifully and is easy to size to any window by adding repeats.
• Blankets and throws: a filet motif worked in DK cotton or a wool blend, at a much larger scale.
• Name and alphabet panels: charts of letters, ideal for personalised gifts and new-baby presents.
• Shawls, tops and bag panels: where the drape of the open grid does the work.

Yarn and hook choice

Fine mercerised cotton with a small steel hook gives the crisp, formal look of traditional filet, and is what most vintage-style charts assume. Working the same chart in DK cotton and a 3.5mm or 4mm hook produces a much larger, softer version — useful for blankets and wall hangings, and far easier on the eyes. Cotton is strongly preferred over wool or acrylic for filet because the grid needs to hold its geometry; a springy yarn lets the squares distort and the picture becomes hard to read. Whatever you choose, swatch a small block of ten squares by ten and measure it, so you can predict the finished size of the whole chart.

Keeping the grid square

Filet lives or dies on even tension, because the eye reads any drift immediately in a grid. Two habits help: count your squares at the end of every row rather than every ten rows, and place a marker at regular intervals (i.e. for every repeat, or every twenty squares) on wide pieces. Chains should be worked at the same tension as the trebles, not looser, or the spaces will gape. When you finish, blocking is essential rather than optional. Pin the piece out damp to true right angles, measure the diagonals to check they match, and let it dry fully. A blocked filet panel looks like a different object from the one that came off the hook.

Finishing and care

Edge a finished panel with a round of double crochet or a simple picot to firm up the outline, and add a casing or a row of large spaces at the top if you are hanging a curtain on a rod. Weave ends into the solid blocks rather than the spaces, where they would show. Cotton filet washes well by hand or on a cool machine cycle in a mesh bag; reshape damp, block again and it will look new. Store flat rather than folded to avoid permanent creases in the grid.

Filet crochet questions

Are there free filet crochet patterns to download? Yes, free PDF charts sit alongside paid designs in this collection.

Is filet crochet suitable for beginners? Yes, provided you can work a treble and a chain. The difficulty is in counting and consistency, not in the stitches.

What yarn should I use? Cotton, almost always. Fine cotton with a steel hook for traditional lace, or DK cotton with a larger hook for blankets and hangings.

How do I know how big it will be? Crochet a ten-by-ten square sample, measure it, and scale up by the number of squares in the chart.

Why does my work look skewed? Usually uneven chain tension or a miscount. Count every row, and block the finished piece to true right angles.
