Last summer my six year old worked with grandma to create no sew skirt for herself. Recently she created one for her stuffed hedgehog. First she cut a piece of elastic to fit the waist of the hedgehog. She did sew it into a circle, but a safety pin could be used if no sewing at all is truly desired. Then she cut strips of tulle fabric and tied them in knots to the elastic.
This photo shows the skirt half completed. Here's a link to the one she completed for herself.
