Lynn Roddy Brown has a method for making HSTs that is quick and easy. She uses the Quilt In A Day Triangle Square Up Ruler. I like that ruler because you square the block up before you press it open.
I also have the June Tailor Perfect QST and HST ruler. I like it for drawing and cutting the center line, but I don't use it for squareing them up.[/quote]
I use the QIAD Triangle Square Up ruler and you can make 8 HST at a time and you use the seam line to trim the HST before you press, it is perfect on every square because it is squared up before you open it out to press. No bias edges either.
