I am making a purse with a flap; it is a single piece : front, bottom, back, top, flap.
I have planned to use 1.5 (,maybe 2.0) mm glued flesh to flesh 3-4 mm). The pieces are pretty firm but on each of the 5 sections I will imbed stiffener/tandy. On the panels but not in the folds.
It came to me that it gets folded into it's box shape I might have a problem that comes up in bifold wallets that are f2f them folded.
I did some tests on scrap and it seems ok : the inside piece compresses some and the outside stretches some. The wrinkles are minimal. The two pieces will be hand stitched at their edges and the two pieces will be glued f2f.
What are your thoughts on durability, do ability?...; Similar to bifold wallet.
