I had done two of the next four designs before so those came easier and I find they look better too. I definitely found the other two (Spiral Illusion and Lightning Bolts) more challenging, which was perfect because that was what I was hoping for with this project!
Here's my progress (by the way, I know I'm not supposed to quilt in the white border, but I did my first four like that so I'm going to do all of them this way for consistency):
Once again, I found that I really didn't like my stitching in the midst of doing the design, but once I was done and stepped back, it didn't seem to look as bad as I thought. Do you find that too?
