I will say this...if the leather isn't consistent in wetness there will be areas that are dryer and the effect of the tooling isn't consistent. That's why I wait for the bubbles to stop. Just my experience.
I get the best results waiting for the bubbles to stop. It only takes a few seconds. I usually put it in the bag overnight. When I know I'm going to be ready to carve I get it out and let it sit in the open air until it's just right. I usually put the grain side down and check it often until I think the time is right.
I don't envy you any! Sounds like this is the customer from you know what! Do you have the invoices from the transactions? I would not pay anything until you get a lawyer.
I use a plastic zippered bag left over from purchasing a king sized bed cover. It works perfect for my project sizes. I just submerge my leather in warm water till it stops bubbling dry it off with a towel and insert it into the bag. I've never had a problem with mold and mine have stayed in the bag for days.
I have stumbled across a (lot) of Italian leather actually from a tannery in Italy. This leather was for major furniture factories in the Carolina's. These hides are full hides. She wants $100 a hide. Think it's a good deal? Would like some comments please! Thanks
Good question Rooster...I see what you're saying. This may be unorthodox, but what if you stopped up to a point and raised the presser foot pulled out extra thread and hand sewed the finish?! Don't know how how convenient that is but it might work.
