I hate spending money on something I can do quite as well. I just made 396 HST by drawing a set of squares (3x3) in a grid on the lighter fabric, drew the hypotenuses (hypoteni?) then sewed a quarter inch to each side of the hypotenuse, pressed, then cut apart and pressed open. It was pretty quick and the money I saved on thangles (paper to buy to throw out? Not my style) can be used elsewhere (think: fabric--woo hoo)
