I have a video tutorial of the seaming process! Check it out here!
To begin, you’ll need a pair of 5mm (US 8) knitting needles and less than a typical skein of worsted weight yarn like Paintbox Yarns Simply Aran, as well as a tapestry needle for seaming.
Cast on 19 sts for the newborn-6mo size or 23 sts for the 6mo-12mo size
Row 1: Knit all sts
Row 2: Knit all sts
Repeat in garter stitch until your piece measures 1.75in (4cm) about 14 rows
On the next row: k1, p1. repeat to the end of the row
On the next row: p1, k1. repeat to the end of the row
On the next row: Knit all sts
On the next row: Knit all sts
Repeat in garter stitch until your piece measures 1.75in (4cm) about 14 rows.
Bind off leaving a long tail for seaming.
Thread a tapestry needle with your yarn tail and whip stitch the cast on and bind off edges together to make a tube.
Then thread your yarn around and around one of the open edges of the tube to draw it closed like a drawstring. Knot the end and cut the excess. Turn your project inside out and you’re done! (well, you gotta make another one)
