It was really very easy to make. Don't be afraid to try it! I wound up taking one row off the width because it made the proportion strange. It's almost perfectly square, a lap size, I think. I think I probably should have trimmed each row to be narrower, but I'm pretty happy with how it came out. I used just one jelly roll and supplemented with just a couple fabrics of my own (like the border fabrics).
Thanks for all your comments. There were times I was ready to just put this one in the WIP drawer and forget about it. If I can do it, ANYBODY can!
For Melissa, here are some pics of the curtain and the wallhanging in my sewing room. Sorry, the window pic came out kind of dark!
