My stash is mostly FQ's and 1/2 yards... for small quilts, and many were given to me by quilter friends. When I want to make a big quilt, I go shopping...
And I love my little stash! It's fun for me to start pulling fabrics out and seeing how they spark each other. Much easier for me than going to a shop and searching...
I can lay out some pieces and meditate on them for a few days before deciding which ones I want to use for a project.. Works for me...
