My first quilt teacher said never to throw anything out & let me tell you that stuck with me! I saved, I saved & I saved! I did use some of it & later when I started applique, it came in handy! But you have to draw a line as to how little of pieces you are going to save. I think we all go thru this. I had a girlfriend that saved 1-1/2 - 2-1/2" strips for later use like others in this thread. Then later used them for another scrappy quilt. Just depends on the sizes I guess......
