Description from Knitty.com:
A boxy, cropped cardigan for little girls and boys. Haiku is an easy project for novice knitters.  It is worked side to side, mainly in garter stitch, and requires very little finishing work.

Haiku is designed to work with any yarn and the appropriate needles. A chunkier yarn will give you a quick knit and a bulkier sweater; a finer gauge yarn will yield a more elegant sweater.
