no link; the pattern doesn't say.
I have the garment and a knit square. the pattern does not specify how to attach said square to the garment.
Here is a snippet:
Row 1: (k1, p1) across.
Row 2: (P1, k1) across.
Row 3: Repeat row 1.
Row 4: P1, k1, p1; k to last 3 stitches; k1, p1, k1.
Row 5: K1, p1, k1; p to last 3 stitches; p1, k1, p1.
Repeat rows 4 – 5 until desired size.
Finish the pocket as follows:
WS: K all sts.
RS: K all sts.
WS: BO in k. (Bound off edge is the top of the pocket.)
So I have the garment and this pretty knit square.
