Oh, sorry - just realised its not a pattern just pictures of the finished bag. You have to buy the pattern, - but actually it looks fairly straightforward, I don't think it would be hard to draw up your own pattern, its just rectangles basically.
I'd also have to buy a sewing machine Mine is in the loft of my parents house overseas! I think I might ask Santa for one for Christmas! looks at bank account, decideds Santa will probably say Ha Ha Ha instead of Ho Ho Ho
