My daughter and future SIL have two rescued bunnies as pets. She asked me to make her "bunny quilts" that she could use in the bunny pen for them to run around on. She was using old sheets, but they are not stiff enough, and the bunnies bunched them up.
So I took old sheets, top and bottom, and my first practice quilts went to the bunnies. I practiced different size designs and movements, and figured out the tension issues. (I only have a mid-arm, but the theory is the same.) And my first two quilts went to the bunnies, who are chewing up the edges, but they are holding up after being washed once a week!
