I save all my batting scraps, then fuse them with batting tape to use again in another project. I've made lots of placemats using leftover fabric and batting. This week I am working on a QAYG quilt, using leftover batting cut into 5" squares.
I bought 10 yards of batting about 6 months ago and am just now using the last of it. Only thing left are "schnibbles" as my Oma used to say (tiny slivers and pieces).����
