I use a size H hook, but you can use whatever size you desire. Keep in mind there a some skipped sts with dc's, so depending on how wide you want the gaps to be, choose your hook.
Scarf Pattern:
Row 1: Ch as wide as you would like the scarf to be (this is for width, not length). For baby scarves, I chain 16, for adults, 32 is generally a good width. Turn. Row 2: 1 Sc in second chain from hook and in each chain to end. (15 sts) Turn. Repeat Row 2 two or three times if you would like to sew an applique to the scarf. Row 3: Ch 1, skip 1 sc, 1 dc in next sc, repeat to end of row. Ch 1, Turn. Row 4: 1 sc in each ch to end of row. Turn. Repeat rows 3 and 4 until you get the length of the scarf you desire. Last row: 1 sc in each st around the scarf (sides, bottom, and top) Fasten off and sew in ends.
