Starting a Wonky-Cross Quilt

I haven't been doing much quilting these days - but I did start a wonky-cross quilt after seeing a picture of Karyn's online. Mine probably won't be finished until next winter. But I did want to try making a few squares just to try the pattern. Now I realize that I need more variety - some crosses (or "pluses") wider, some narrower. I like green... But is it too bland? I did a google search and found another "wonky cross" quilt in red and white... I am drawn more to bright colors! Should I switch to a new color?

Karyn's is wall-hanging size. How would this green one look if it were bigger? For a single or double bed...? (So many decisions!)
