Several readers asked about the fabric in the previous post. It is actually the reverse side of a duvet cover from overstock.com. When I found it, they only had twin size, so I ordered two and Wendy sewed them together to fit my king-size down comforter. My bed is a queen, but I use a king comforter for full coverage.
Anyway, I see that overstock is completely sold out now. Sears has the pattern in a comforter set, but I've been unable to find the duvet cover anywhere. Sorry I couldn't be of more help!
