Calculation of Stitches to Be Picked Up
If you find that your edging is too short (causing the main fabric to pucker) or too long (causing the main fabric to splay), calculate a new pick-up rate. All methods: Cast on 3 stitches. Work 6 inches of your chosen edging (I-cord, double-knit or stockinette stitch). Work as a standalone strip, not applied to any other fabric, as follows: For I-Cord Edging Row 1 (RS): *K3, do not turn; slip sts back to LH needle and bring yarn around the back ready to work next row; rep from * until I-cord measures 6 inches. For Double-Knit Edging Row 1 (RS): K1, sl 1 wyif, k1. Row 2 (WS): Sl 1 wyif, k1, sl 1 wyif.
Rep Rows 1 and 2 until piece measures 6 inches. For Stockinette Edging Row 1 (RS): K3. Row 2 (WS): P3.
Rep Rows 1 and 2 until piece measures 6 inches.
Mark the middle 4 inches of unstretched piece, then count the rows in that 4 inches. Divide the number of rows by 4 to calculate the number of rows per inch. Now measure the length of the edge to which you want to apply the edging. Multiply the length of the edge by the number of rows per inch in your edging.
If working either an applied I-cord or double-knit edging, this is the number of stitches to pick up along the edge of your main fabric.
If, however, you’re working an applied stockinette edging, divide the number of rows per inch by 2. The reason for doing this is that you’ll be working two complete edging rows for each time the edging is joined to a picked-up stitch.
