Stephanie from The TipToe Fairy shows how you can make a pretty twirly skirt for an American Girl or other 18″ doll. You can probably find the pieces you need for this in your scrap bin, especially if you have some scraps that are long and narrow. (You could also piece together shorter strips to make the lowest tier which uses the longest strip of fabric.) You can easily adjust the dimensions to fit other size dolls, too. Go to The TipToe Fairy for the doll twirly skirt tutorial.
