Progress is painfully slow. Emphasis on painful. The top has slowly flattened, and it looks as if the edges won't match up. The shako should have a convex top to fit.
A wet sponge and a perfectly-sized plate will fix the issue. The replica onion bottle full of water acts as a weight on the wet top. Edge stitching is massive PITA. The thread tends to tear out if the hole is too shallow. There are hints of a weird pucker developing. Cross your fingers.
