Finally got pics of these, the ones I had left anyways.
The top hats are knit using Brown Sheep Lamb's Pride Bulky (shaved after felting) and Cascade Yarns 220 wool (held double) on 8mm needles.
The mini Tricorns (these tand about 4-5" tall) are knit with Cascade Yarns 220 wool heathers on 8mm needles.
