I have been quilting for 18 years and I know everything, (right). I am putting together a quilt with hundreds of half square triangles. I've made many thousands of 1/2 squares I can do them in my sleep. After about 100 I got tired and bored of drawing a line, sewing on both sides, cutting apart. Well I have a good eye so I tried a few with just one corner to the next, and It worked, Yea. So I made the rest of them and guess what? When I put them together they don't match. So I wasted, time, fabric and my pride is damaged. So I hope you learn from my bloated ego, and do your 1/2 squares the way you were taught.
