What are you most proud of? That all the corners points matched up, and the optical illusion is pretty cool. You can't see it up close, but once you back away, all the different size squares become curvy. What advice would you give someone starting this project? Make sure you are up for the challenge. I tried this as a bargello exercise, and this was NOT my favorite. LOL Sorry. I really struggled through this one. Just work through it, and the end result will be worth it.
