give the samples to a school, church, camp, or girl/boy scouts group for art projects
Put it on craig's list for free, someone would love to use them for a project or quilt
put the pieces in smaller bags and give to good will
If it's a natural fiber, compost it
ask an animal shelter if they could use them for bedding
see if a local quilter or quilt guild can use them
See if a church group is making donation quilts and if they can use them.
There are other possible uses that others may have.
