This is wonderful! Thank you so much for sharing this, I'm trying to make something nice for four individuals at my college who have helped me out so much, and this will mean I will actually have time to make them something other than just a table runner. Love the idea, thank you for sharing!
and this is doubly awesome, because I've discovered a super fast way to construct HST's (it's basically the Wonder Ruler method, only I'm just using my regular ruler that happens to have a 45 degree mark on it), so I'll be able to do this in no time flat.
