Because this year's RSC Sampler quilt is limited to just three units: squares, rectangles, and half square triangles, I have been thinking of all of the different ways people make half square triangles. I'm starting a collection of tutorials, so let me know if your favorite method is not on the list and I will add it.
Magic 8 Method - add 7/8 inches to your finished size and multiply by 2
Square Sewn in the Middle Method - add 7/8 inches to your finished size
Two at a time without drawn lines - using a laser to mark the line
Printed Paper Method - Pattern is printed on paper then sewn and cut
Sew Around the Edges of a Square Method - leaves lots of bias edges, but seems nifty otherwise
Fons and Porter (video)- cuts both HST and QST as well as the strips
Easy Angle (video) - cuts units from same strip size as the square units in your block
