Stitch Masterclass: Interlocked Filet Crochet

Make your projects proud with this perfect pattern: Interlocked Filet Crochet

Filet crochet is a fabulously easy way to create very detailed images with yarn – worked from charts, it’s much like colour work or cross-stitch. However, filet crochet is only usually worked with one colour, making it’s design potentially much subtler in the end result. Through using similar techniques, interlocked filet introduces a way to bring colour into the mix, and while, you’re not likely to use it to produce the detailed picture designs of traditional filet crochet, it gives you a intriguing way to bring pattern into your next crochet project. We’ve got the basic technique and a few extra ideas to share with you here, but there’s lots of intriguing ideas you can try using this technique once you’ve mastered it!

Hints and tips

  • Your CC chain hould always be on the WS of the next row to be worked – if it’s wrong, simply unravel the last MC st and rework once on the right side of the work.
  • Interlocked filet creates a reversible pattern, with the design on the wrong side in the reverse colourways. In that way, it’s similar to a knitting technique called double knitting.

The basics

The basic pattern of interlocked filet creates small squares of contrast colour (CC). This is a reversible pattern, which would make it great for the likes of a cowl or scarf where both sides will be seen. The main colour (MC) and contrast colour are not joined at any point in this pattern – they’re rather held together by the weaving technique used.

Let’s have a go

Step 1:

With MC, chain 3 + multiple of 2 + 3.

Step 2:

Row 1 (MC): 1 tr in 6th ch from hook, [1 ch, 1 tr] across. 4 ch.

Remove from hook. Place a stitch marker in loose st throughout to stop unravelling if desired.

Step 3:

With CC, chain 2 fewer than MC starting ch. Weave through Row 1 of MC from front to back to front as pictured, ensuring 4 ch at the end for turning chain.

Step 4:

Row 1 (CC): Working into the back of the work only, 1 tr in 6th ch from hook, [1 ch, 1 tr] across ensuring each st is placed in between a separate set of tr from Row 1 of MC. 4 ch. [5]

Remove from hook. Place MC back on hook.

Place MC back on hook.

Row 3 (MC): Working alternatively into front and back of work, [1 tr in next tr, 1 ch, miss 1 ch] across. 4 ch.

Remove from hook.

Rep MC rows 2 and 3, and CC Row 2. Each 4-row repeat will make one set of squares on the RS only.

Shifting squares

 To make the squares move along for each 4 row repeat, switch the order of MC Rows 2 and 3 for every 4-row repeat. On the wrong side, this will create a Geometric chevron design on the wrong side.

To make this wavy chevron design, repeat MC Row 2 only in each 4 stitch repeat (which means, don’t switch to MC Row 3). If you change to MC Row 3 instead of MC Row 2 for the next 4 row repeat, the waves will reverse direction.
