Me personally, I don't save anything less than a 2 inch square piece with the idea to reuse it in a quilt someday but I do toss all those bits and pieces into a bag and use them for dog/cat pillow stuffing or pincushion stuffing. I try not to waste when ever possible.
When I make pet pillows, I use a heavy duty canvas type fabric for the removable outer layer so it can be washed when needed....not the stuffed part of the pillow...I don't think it would ever get dry!!!!
