Hey guys, i need help with the preservation of a shed Boa snake skin, thing is im using it in craft so i cant put it in a jar, im planning on making a sort of snakeskin armband but no natural snake makes the skin i need (diamond shapes but made up of red, blue, white, and black in a specific pattern), so i figured the easiest way was to get a shed skin, use some sort of paint/nail polish on the inside, and then glue it to some fabric, but then i realised the actual skin would probably perish at some point, so how would be the best way to preserve it? or make it look like a real skin?

thanks for any help you can give me
