Most of what I do is with socks: Sock animals, sock characters, sock people. However, occasionally I come across other material that is just so perfect for something that I'm willing to break my own rules and try something new.
Someone donated three scarves to my creative stash of supplies. The green color immediately reminded me of Oscar the Grouch (Sesame Street), the blue was definitely Cookie Monster color and the white, shimmering scarf reminded me of that monster on the old classic Rudolph The Red Nose Reindeer movie (1964).
I made the basic bodies for these characters from socks, stuffed them with the regular stuffing that I use and then covered them with the scarves sewing them down into the sock material. They were fun to make and stood about 12" tall when they were done.
