This is how I make them... and I'm a novice... they come out really nice... To make Quarter square triangles, you simply repeat the process... Place the two HSTs right sides together, draw a line perpendicular to the seam from corner to corner, sew 1/4" on each side of the line, then cut on the line...
The only thing is, I can't remember how large to make the original block to get the size HST or QST you need... My QSTs started out as 6 1/2" blocks and ended up 6" blocks... I guess the 1/4" seams explains that... (not a math person..sigh)
Just finished the blocks for a dog bed out of old jeans using this technique...
