Increases and Decreases in Filet Crochet
Written by the Filet Crochet Chart Builder team · Updated
Most filet charts are worked over a fixed number of squares, but shaped pieces — scalloped edges, stepped borders, or contoured motifs — add or remove squares at the ends of rows. The techniques are simple once you separate edge changes from the body of the row.
Increasing a block at the start of a row
To add a block at the beginning of a row, chain extra stitches before you turn (enough for the new block plus the turning height), then work double crochet back across those chains to create the new solid square before continuing along the chart.
Increasing a space at the start of a row
To add an open square instead, chain the width of the mesh plus the turning chains, then work a double crochet into the appropriate stitch to leave the new square open. The principle is the same as adding a block — only the new square is left as mesh.
Increasing at the end of a row
Adding squares at the far end uses a foundation built from the base of the last stitch — a chain extended out from the final double crochet — so the new blocks or spaces continue the row in line with the rest of the fabric.
Decreasing at either edge
To remove squares, simply stop short of the chart edge: slip stitch across the squares you want to drop at the start of a row, or leave them unworked at the end. Counting the remaining squares against the chart keeps the shaping symmetric.
