It's one thing to have an idea, it's another to be disciplined enough to take a photo of each of the stages, then adjust the photos, insert them into a document and write up the instructions. That's before I start on the pattern. That involved peering at the pieces and gluing together shapes in MS word. Not ideal, but it works for me.
I think I may try making myself a version in a fabric that's a bit more "grown up". I think it would make a great evening bag. What do you think?
