Something that we do in our guild is to save all of our scraps, batting, thread, etc. We then use fabrics we want to get rid of and cut two 14" squares. Sew around them, leave an opening, and stuff with leftover scraps. Sew the opening closed and all of a sudden, we have dog beds. I guess any size would do but this shelter asked for 14" squares to fit into the cages. The shelter just tosses them in the washer and dryer and uses them again. It has helped me to clean out my fabric easier because I will part with scraps for this project instead of keeping them. Check with your local shelters and find out if there is a need.
