Well, I was so excited about finishing this project, I didn't notice that I had sewn the last row of squares on in the wrong orientation >.<
Other than that, I'm happy with the way it came out, and I think it looks very nice it its intended location. It's all done with two strands of RHSS, except for one strand of Vanna's Choice in the trim:
Trying out granny squares has taught me one very important thing: I never want to deal with yarn ends ever again! From now on, everything I make will be monochrome. Or else I'll tell everyone that dangling threads are the latest fashion. I can see the headlines now: "The Latest Trend? Lots of Loose Ends!" If we all do it, we can make it happen, so who's with me here? ;D
