I had a gal send me some hearts (for charity) she had simply just cut them out after she had sewn a bunch of random pink square scraps together. I stabilized them by sewing a light-weight interfacing to the heart (rst). After carefully slitting the middle of the interfacing, I then turned them right side out pressed them and appliqued them onto squares with a simple hem stitch to the edges. They turned out really nice! I will find the link to the runner I made with them for the auction.
Here is the link...
