I have hit a snag though. When I was drawing out the pieces I discovered why it's not recommended for stripes. Basically, the outside yoke is cut on the bias so any pattern there will look really odd with the rest of the top. I'm going to make one out of my nice flowery cloth but I'm going to keep my eye out in the fabric shop and pull out some other patterns for my stripy fabric.
I'm not sure what I'm going to do with the blurry black and grey stuff.
