My friend Dorothy does alot of my prep work for me and when I give her fabric to cut for making Blocks she will look at it and see the holes or jagged areas and say:
Well it looks like a little mouse has been at it again! LOl
I am always hacking off a small piece here and there. I always have ragged looking fabric! I might need a piece that only that only that fabric will allow me to cut it out. I leave the ends and odd shaped sections because I might need to cut a long piece and that odd shape might just give me enough room for the length I need.
