wet forming leather for a lighter case

in this video i wet form a piece of leather to make a leather lighter case.
here's a couple tips on doing it
1. when wetting the leather saturate it to where it changes to a shade darker, do a couple of them and you start to see how much water it can absorb.
2. using those metal clips makes a nice little indent in the leather that sticks around for awhile that you can use as a guide for when you punch the holes for sewing.
