Crochet filet stitch
Maybe also called an open mesh stitch.
Larger Filet Stitch
Note: This tutorial is based on working a 4 double crochet mesh.
Foundation Row: You need to crochet a multiple of 3 chains + 5
Row 1: Foundation Row
Note: I crocheted a beginning chain of 17 for the tutorial
Step 1: (How to begin your foundation row) dc in the 8th chain from hook – This forms your first Open Space/Mesh
Note: The first 5 chains (3 chains for the turning chain, which also counts as the first double crochet at the beginning of the row, plus 2 chains for the top chains of the open mesh).
Note: When counting stitches on a chain, remember that the loop on the hook and the beginning slip knot is never counted.
Step 2: Chain 2, skip 2 chains, then work a double crochet into the next chain.
Step 3: Repeat this across till you come to the end.
Row 2:
Step 1: (How to begin each row form after your foundation row) chain 5, (which counts as your turning chain + chain 2) skip 2 chains, then work a double crochet into the next chain.
Note: This will form your first open space/mesh
Step 2: Chain 2, skip 2 chains, then work a double crochet into the next chain. Repeat this across till you come to the last Open Space/Mesh.
Step 3: Chain 2, skip 2 chains, then work in a double crochet in the top of your turning chain.
Repeat row 2 until you have desired length.
