I got it at my LYS in POrtland Oregon
Someone made it up for a class and they gave me a copy of it before it was ready. I don't know if it is a free pattern or for sale but it is copywrighted so i can't just give it to you even though it is SO easy I have it memorized.
it is by Sue Olsen and is called Seed Stitch Cable Purse.
Here is the website of the store I bought it at www.theknittingbee.com
Maybe you could e-mail and aske them where to score a copy?
