I have tried several ways on making 1/2 square triangles. Why do most of the helps like Thangles, Easy Angle & Tiger tape say to add 1/2" to strip measurement before cutting out? Then they come out too large, all have to be trimmed down. Isn't that a lot of extra work? I have used the Angler 2 in the past, that fits on the bed of my machine, and had fairly good luck but just wondering about trying one of these other methods. What is the method you use or what works best for you. Just curious. Appreciate your help.
