Great for yarn bombing!
Ok, they're as useful as a chocolate teapot, but they look cool and make great ornaments!
Here's how to knit your knitting needle. With 4mm (US6) needles and double knitting yarn, cast on 3 sts.
Row 1: K.
Row 2: P.
Row 3: incr in each st - 6 sts
Row 4 and all even rows - P
Row 5: k1, incr in next st, rpt to end (9 sts)
Row 7: k2, incr in next st, rpt to end (12 sts)
Row 9, k3, incr in next st, rpt to end
Row 11: k4, incr in next st, rpt to end (18 sts)
Row 13: k5, incr in next st, rpt to end (21 sts)
Now knit straight in stocking stitch until needle is about 20 cm long or so - up to you! Shape the head:
Row 1: k1, incr in next st, rpt to end
Row 2: P
Row 3: k1, incr in next st, rpt to end
Row 4: P.
Work 6-8 rows stocking stitch. Now decrease:
Row 1: K1, k2tog, rpt to end
Row 2: P
Row 3: K2tog all way across
Row 4: P
Row 5: K2tog all way across. Cut off long end, thread through the remaining stitches and pull tight. Use the end to sew up the side of the needle, leaving small gap for stuffing.
On the largest needles you've got, cast on and work a few rows in either fabric strips (I used cut-up t-shirt) or very thick yarn. On the last row, wrap wool 3 times round the needle as you make the stitch. This leaves you with a nice big loop when you slip the knitting off the real needles and onto your knitted ones.
