Hang on in there, you can do it.
Whenever I have leftovers, I do cut 2 1/2" squares out. Put them in different containers, do I don't have doubles. I have three stashes.
One for me two for someone else. Eventually I will have more than enough to make a quilt. With this, I don't have to cut all the little squares at once. (Which would drive me crazy!)
But you can do it, imagine your quilt, how pretty it will be, this will inspire you not to give up!
