This gives more volume to the compartments without the extra work of sewing in gussets. The straps were no longer with the pouch when it was received by the museum. The original buttons were metal with a loop back. The pattern shown in the accompanying drawing is actual size. The back and the flap are, of course, one piece, but for the space restrictions of this publication are shown with the flap folded over.
Construction is obviously quite simple.
The tabs on the back are easier to stitch if they are sewed in place before assembly. You will still have to use an awl even with the glovers' needle, but it will be easier. Otherwise the thread on the blunted needle will be cut by the sharp edges of the glovers' needle. The most authentic thread would be linen in 2 strand twist-bees waxed. Our bag is very dark from age.
