Large leather plate mould.
The inner size is: 10" x 7" x 1.2" ( 26cm x 18cm x 3cm ).
The weight is about 3KG.
I advise 4mm (10 oz) leather, if you don't have 4mm leather, you can glue 2 pieces of 2mm (5oz) leather flesh side to flesh side, then the plate will be better looking.
How to make it?
Step 1: Wet your vegetable tanned leather absolutely in a pool or basin that with water.
Step 2: Put the wet leather in the mold and fasten them with in jack machine, after than, use G clamps or a vise to fast it 4 hours or more time.
Step 3: Loosen the G clamps or vise and take out the molded leather.
Step 4: Cut off the redundant leather :)
Note: It needs to wait 7 days to make this mold if there is no in store.
