This link above give directions for making something like this one, its not one that I have a pattern for yet. Its in the works.
The pattern link above on this page could be a primer for anyone not having tried to reuse any cloth from clothing. I'd use new fabric for the rectangle backgrounds and then recycled for the hearts. Fuse a stabilizer to the back of your hearts and carry on. Simple and you've just done your first project reusing cloth from clothing.
