Have you seen this? It's called Easy Start - and it does just that. No more fiddling around in the middle for the end of the ball, no more giving up and using the yarn from the outside ... and then spend ages chasing it round the floor and fighting the cat for possession of the ball :) Wise Badger - Patons Merino Extrafine DK, £3.95 (http://www.wisebadger.com/patons-merino-extrafine-dk-101-white/)
The Little Doodah Millie Amigurumi Pattern, 4 1/2" tall with fingering yarn. This is one of the cutest little amigurumis I've ever made. The pattern is perfect! I made it with sport weight yarn and it turned out just over 4" tall.
