Ta. Yep, it's only one layer JD.
I sat up late last night and thought stuff it, I'm finishing this. It's only one layer and atm laced together with thick sewing thread to get the idea. It should fit Becky nice as the lady in the shop is a similar size. She just helped me put the shoulder things on and then I did the rest.
It's folded back on itself where the rivet eyelts are and the rest of it is just facing that's glued back on itself. Seamstress' idea, and it's a good one!
