some people even plan on using the wrong side a print in order to get a lighter version of the same print for a perfect color match in a different value.
I just did that this weekend. I was looking for a yellow in my stash for a quilt I was working on. Everything was just too dark. I finally thought about looking at the backside and found the perfect shade. The only problem is that I'm so accustomed to RST, that I sewed 2 strips on backwards and had to get out my frogger.
