IMHO...the way you are doing them is waaayyyy too much work. Just do them the way Scissor Queen suggested, sew a long chain of them, cut them apart, press, then trim them to size using your 45 diag. line on your small square ruler. I promise you....this works...I've made tons and tons of them this way. Good luck and do find a way to do it and still have fun, quilting is supposed to be FUN..not stressful or frustrating!
