What to do with all the bits and pieces.....

I seem to accumulate a lot of snippets when quilting.  I could maybe use some to make very, very tiny blocks, but instead I use them to stuff pillows for an animal rescue center.  The pillow is made up of practice pieces created when I am working out different quilting designs.  It is a win-win for me and for the animals.
What do you do with the scraps?
