I made two sizes of Purl Bee's Lamb Bonnet, one for a friends daughter and one for myself. They came together in an afternoon an were super easy to sew. I used a walking foot like suggested and had no problem sewing the fleece. The main part of the bonnet is the Winter Baby Bonnet with added lamb's ears. I will definitely be sewing more of these in the future and I'll give the Winter Baby Bonnet a try as well.
