First of all, I’m not a taxidermist. I’m a leather craftsman. I was asked to make a belt with snake skin inlays. The customer provided the skins (from 3 snakes) in a ziplock bag... frozen... and I was told they were tanned already. To be sure, I asked for info and was given the name of the taxidermist that tanned the skins. I contacted him to confirm they were tanned and I was told they were tanned with Krowtann. Assuming all was well, I thawed the skins and hung them out to dry... only to later find them shriveled and hard as a board. Soaking them in water restored the flexibility... but fearing they’d harden again, I tried soaking one of them with neatsfoot (since it softens leather, I thought I’d give it a try). No luck... I’m left with an oily shriveled skin. I need a DRY, flexible skin to glue to a belt. Is there any way to fix what I have?
