So far the printed treasures photo fabric has worked well for me. why not try finding a rabbit pattern from a coloring book or somewhere and make a fluffy bunny out of fleece or flannel. Each bunny could be a different texture even corduroy. You could use a color from your hearts. Give me a pm if you want fleece (sweatshirt) material. My mom has a bunch from when her grandkids were little and she made outfits for them. I do like the idea of both a quilt and wall hanging. Was the applique easy? I did some 20 years ago for a baby quilt but can't remember how and now I want to do some again. Love the fabric and wreaths, good luck with the rest of the project.
