Oh, one quick addition:
This is the best corner I've done:
Best part is, that was not only totally intentional, but on the first try, too!! It was shortly after doing this that I decided to redo the heart - before I'd used some boring fabrics that didn't really make it stand out for what it was. I went back to Joann's to find some other stuff and got inspired by some polar fleece remnants. I debated doing a similar style the flannel quilt you made me, but I figured I'd just stick with the basics for now. Corners involving quadrilaterals (not squares) still give me issues, but I think I'm getting the hang of it. I'm so excited to give this to you. I can't wait til Christmas!!!
