I didn't find a light green that would work, but I found a lavender.I think I'm going to use the green for the smaller border with the lavender in the center. I like it better (I think) than the darker purple.
I've been very distracted studying German...trying to keep the mind active...so haven't been doing much quilting. If I could find a good audio only way to learn, I might be willing to quilt while I listen. I have some that I've found online, but they are BORING.
