Hello. You can also donate to Quilts for Kids. They accept fabric donations, which will be made into quilts and donated to kids in the hospital.

The following excerpt is taken from their website.
"If you are someone with a stash of fun child-oriented fabrics: Is there fabric taking up valuable space in your closet that you intended to use in a quilt or other craft project? Don’t feel guilty about not doing the project—donate it to us to be made into quilts for the children we serve. You can even take a tax deduction for this! Send the fabric to headquarters or contact your local QFK chapter. Fabric has to be “new,” unused, and not clothing or draperies,etc."
