I am going to go to Hancock's and Joann's if necessary to find it (have printed off a picture just to make sure I get the right one), but how much do I need to get? I know it depends on the size of the finished quilt, so what do I need for a double? If I can find the fabric I will join in when I finish the Dances with Waves Project Linus quilts and an outfit for my granddaughter.
