Love it!
Not sure what you could use for fabrics, but you could also cut squares of the black and red, and silhouette stitch "positions" -lips, even x's and o's for hugs and kisses, playboy bunny ears...you know what I mean! Also, sew black lace pieces over the red and vice versa, making lace squares.
To the poster who said "too old" -- no way! Never too old for fun! ;)
