Throw them away???

What can be done with the fabric scraps you do not want?
If they are too small to work with, you could just throw them away.
But, there are some "greener" alternatives:
--Check with your Humane Society to see if they take "dog pillows."  If so, make a pillow casing from unwanted fabric and stuff it with all your fabric scraps, even those pieces you trim off as you are squaring up your quilt blocks or trimming seam allowances.
--Is there any organization in your area that collects scrap fabric because they can sell it and get $$ for it?

If you have larger fabric scraps that you have decided you do not want:
--find a group that makes charity quilts (your church, for instance).  They will welcome your fabric donations.
--pass your unwanted fabric on to a quilting friend who likes to work with scraps or one who likes to make miniature quilts. 

Since quilters were the original recyclers, we should do our part to keep fabric scraps from the landfills...
