Hello! I am new here and i have a question. Is there any way to preserve and keep a bird skin (with feathers on it) pliable? I don't want to mount it, just keep the skin. I want it to remain flexible in some way. I understand borax will dry the skin out completely, right? So it will be brittle and inflexible. Is there any way to keep the skin flexible without the use of bird tan solvents? I read somewhere vinegar+water+i don't know, which would work, but i don't know what to mix to vinegar etc. I am willing to experiment or take risks, so if possible can you tell me some household materials to work with for this? Read about oils too. I am more interested in the old, traditional way of making this not the too modern chemical way. Bird skin tanning in traditional way maybe? Or anything that will keep it flexible enough. Thanks!
