your little half heart template is great....but rather than spend time doing all that marking, just go from corner to corner with a little "swoop" inbetween" and and you have done what handquilters called the wineglass (at least that is what I have been told).......you can do a whole bunch of these connected squares.....go across one, down and around to next block, across, down and around, when you get to end.....just swoop the bottoms and edge to where you began. There are places, I am sure on the web that will describe this "trip" better than I just did, but saves a lot of time ......have fun with your new "red"
