Any simple knitted or crocheted baby hat pattern will be gratefully received, although we recommend the ones outlined here as it features a ribbed and stretchy band that can be rolled up to double the warmth for a newborn and rolled down as the baby grows.
The approximate measurements suitable for a newborn are 12cm wide, by 17cm high (including a 5cm band).

Using: 8 ply wool
Needles for knitting: 3 mm - 3.5 mm
Cast on 64 stitches.
Work 16 rows in (K2, P2) rib.
Knit 26 rows in stocking stitch (1 row knit, 1 row purl).
Shape the crown as follows:
Row 1: K6, K2tog β repeat to end of row.
Row 2: Purl.
Row 3: K5, K2tog β repeat to end of row.
Row 4: Purl.
Row 5: K4, K2tog β repeat to end of row.
Row 6: Purl.
Continue decreasing in this pattern (knit one fewer stitch before each K2tog on knit rows) until you work K1, K2tog and 16 stitches remain.
Finishing:
Knit 1 row.
Break yarn, thread through remaining stitches and pull tight.
Sew up the seam, ensuring the fold of the ribbed brim is neat and not visible.
