So I made one.
It's a little skewiff - I cut it freehand and did it late at night, but I am very pleased with my interior zipped pocket...check it out people! I had all the random bits and pieces lying around at home (as one does) - leather was from a skirt I turned into another skirt and the fabrics are from Japan and the Lincraft Dee Why closing down sale. The hardware I had to make a bag for someone else, sorry - that project is delayed. Anyway - it's a bag. I didn't need to lay out any more cash for it. And did I mention that interior zip pocket?
