If making so many HSTs, you should purchase the Triangulations CD. You can print out patterns for any HST and use them. I just use regular printer paper. Every single HST will turn out perfect, hardly any waste, and you can eliminate the squaring up process. The CDs is around $30 but well worth the investment. You can use it with so many of your quilting efforts in the future. It has patterns for HST, flying geese, etc., in many sizes. Good luck!
