from DeEtta: I used cotton Christmas fabric to make each of my daughters a tree skirt. I did use flannel in between the layers of the cotton fabric though and the edges looked really good after I clipped and washed them.
You know that sounds like it might help a lot as the flannel is heavier than the cotton and will curl and make the cotton curl too. Thanks for the great tip I might try it one more time. Will let you know how it turns out. Am determined to get one made to my satisfaction. Ellie
