Scrappy heaven!

I don't know why I'm so into making scrappy quilts these days and I love working on quilts that give an optical illusion! This one though, I have to work with the value of the colors to make certain the illusion forms correctly.

I tried to add this quilt design a while back. For some unknown reason the file had not saved properly, so I had to rework it. and looking it the colors now...I think I want to change the yellow to something darker....What do you think? I would like one in tropical blues and greens!!

Opinions!! Let me know!!

Happy sewing!
