Faux Cathedral Windows

I love this sort of quilt but I am so slow in making it. So I have been searching all through the internet for some hints on how to speed me up. I ran across this video and I really like the way she did it so I had to share it with y'all. But maybe you already know how to do this but it was new to me. I wanted to make a tote bag and use this as a pocket on the outside. You know me...gotta have pockets. Anyway, I hope you enjoy watching her as much as I did. Take care
