I bought mine at JoAnn's, then borrowed an acrylic one from a friend. I finally have the quilt on the longarm - it measures 120 X 120!!!!! I don't even know how many yards of fabric I purchased for this quilt or the amount of time spent putting it together - twice - but I know I will be one very happy camper when it is finished. My daughter's birthday is in May and this is for her. She picked out the fabric and the design and I have purchased the fabric from several different places in order to get enough to make it. It has a charcoal gray flannel on the back. If I remember, I will try to get pictures of it when it is finished. I have enough left over to make a runner for her dresser (I think).
I didn't really like the ruler with multiple sizes.
