I did them, and they are so cute!! I fused them to cardboard like Fusible interfacing and fused the back with some scrap fabric, then gut them out. Then I used fusible fleece for the clothes, which I also cut out after I fused it. I then added Velcro to the body and the clothes, with a little magnet on the back of the body for the fridge.
I did them with the new Moda line, but I do have some Aunt Lindy that I'll be doing the same thing with. They are perfect sized.
