Sounds like you are referring to the Daytripper Bag that was in the April/May 2010 issue of Quilt magazine. I bought one recently on eBay. Don't know if there are any more available, but you might be able to find them on Amazon or somewhere else. Below are the links of photos that were shown here on the board. Hope this heops!
