I started cutting and sewing triangles today, using the Easy Angle ruler. My first batch was a mess! I was somehow getting a bowed cut with the Angle ruler. But they were all salvageable with trimming; it's just that one shouldn't have to trim with this method.
The second batch seems to be much better, but I can tell that my ruler placement isn't consistent from batch to batch, resulting in minor size variations. Sometimes it seems that my strips are just a hair too big. I'm hoping for better efficiency and accuracy tomorrow. I will have to pick up the pace if I want to finish by Friday!
