Thank you for all the replies! You guys are fast! One of you mentioned using muslin or broadcloth (instead of the denim) - I had not thought of that, and it might be lighter weight. Denim was just "free" if I could find enough used jeans to cut up! But, the muslin or broadcloth is a good idea too. I'll have to think on it. I will take ones advice and try a few smaller pieces (maybe do some pillows?) and see what I think.
My creative juices are flowing - I hate that when I'm stuck here at work! :-)
