Well, this is not how I'm going to use these, they'll be in a border, not all together, but I couldn't resist playing with the patterns they make. Maybe someday I'll make a quilt with this block ... but the blocks will sure be bigger than 4 inches square!

I would have a difficult time deciding on one pattern though! Which one of these do YOU like the best? Here's one I made last Feb. with hot pink, light pink, and purple triangles in the diagonal. I made some solid squares without the triangle corners to complete my heart - and the use of solid squares opens up a whole 'nother realm of patterns. :)
