I can't remember where I got them from, or find the ones I have right now, but I have crochet patterns for several different outfits for mine. The sewing pattern companies (Simplicity, McCalls & Butterick) used to have them, don't know if they still do. Mostly, I find fabric I like, buy 1/2 yard, sew short sides together, hem one edge, and make an elastic casing on the other. If I remember, 9" peice of elastic worked great, 1/4" wide. I had a bonnet pattern, too. Or a large circle of fabric with elastic stitched about 2" in from edge and stuffed with fiberfill. Makes a simple "girl" goose outfit.
