Instructions:
Make up a standard little hat.

For the bonnet:
Cast on 46 stitches – leave about a foot of yarn.
Garter-stitch 2 rows.
Next row: K2tog to end.
Beginning with a purl row, stocking-stitch 5 rows.
Next row: K1, K2tog to end.
Purl 1 row.
Next row: K2tog to end.
B&T tightly.

Making Up:
Oversew row ends together and turn right side out.
Work short running stiches around the first row of stocking-stitch.
Pull up gathers to fit top of the hat.
Fasten off and sew hat onto body.
Decorate as wished.

An alternative:
Some of the hats are knitted in “mistaken rib” stitch:
Cast on 27 stiches and knit two rows.
Next 12 rows: *K2, P2*, *repeat to end, K1.
(Maureen usually cheats and knits rows 11 and 12 – which will be covered up by the bonnet).
Finish in the usual way.
