The problem I run into with the angle play is cutting them right. Some you cut right side only some wrong side of fabric up...etc. Ive wasted some because of my own fault of not paying attention. There are several I have made but some I wouldn't touch because of the accuracy you have to have with that pattern. To me paper piecing wastes a lot of fabric but if you love the block Id say its probably worth it. I have A thru L or M templates but I usually only use the smaller ones. I like the fact it shows you pictures of the blocks and also what templates to cut of each!
