Here's a corner of the blanket I've just finished for Jackson. As I was in a hurry, I crocheted it this time; crochet works up so much faster, doesn't it? This is the sedge stitch except for the scalloping at top and bottom. The sedge stitch is very easy:
Chain a multiple of 3 sts plus 2 for the base chain
Row 1: Skip 2ch (counts as 1 sc), work [1hdc, 1dc] into next ch, *skp 2 ch, work [1 sc, 1hdc, 1dc] into next st; rep from * to last 3ch, skip 2ch, 1 sc into last ch, turn.
Row 2: 1 ch (counts as 1 sc, work [1hdc, 1dc] into first st, *skp [1 de and 1hdc] work [1sc, 1hdc, 1dc] into next sc, rep from * to last 2 sts, skip [1dc and 1hdc], 1 sc into top of 1 ch, turn.
Rep. 2nd row
(For British terms, convert sc to dc, hdc to htc, and dc to tc. Then say "miss" instead of "skip".)
A different effect can be achieved by using a larger hook; I used the smallest one I could with this yarn because I wanted a tight, thick blanket.
