However, the epidermis may come off, just like when the live animal sheds. This is ok or even desirable since it shows the underlying color and texture better. Old skins can have all sort of problems but it was probably just air dried. (If it were tanned, the skin sloughing issue would have already been resolved.) Unless it has some kind of data or other unique value, I would cut it off the fabric and throw the fabric away. Depending on your use, re-mount or not. <o:p></o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;color:#1F497D'><o:p> </o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;color:#1F497D'>If you are considering fixing the holes, maybe you want to use it as an educational specimen? If so, you can use a silicone caulk (one that will always be flexible) to adhere the skin to a new backing and at the same time add strength. Test the caulk for adhesion strength to the skin with a small dot of it on one if the edges before you commit to gluing the whole thing. This is definitely not a conservation technique but it may help you get use out of an otherwise delicate skin.<o:p></o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;color:#1F497D'><o:p> </o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;color:#1F497D'>If it is data-bearing, still cut it off of the fabric then store it as you would a bird skin—support, acid-free, etc. Many collections roll their skins, which is ok and is definitely the most space conservative but often results in a difficult to use specimen. Wide rolls, like we do with textiles are better than tight rolls. Textile techniques work for flat support too. You can save the sloughed epidermal fragments in an envelope, like an herbarium specimen, if you think it has future use.<o:p></o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;color:#1F497D'><o:p> </o:p></span></font></p><p class=MsoNormal><font size=2 color="#1f497d" face=Calibri><span style='font-size:11.0pt;color:#1F497D'>Though it may be a big skin, note that snakes stretch considerably when skinned and are often intentionally stretched even more.

It is currently thread-tacked to a piece of fabric which is quite soiled. Does anyone have any experience with first, how to keep the scales from coming off, and second, what would be the best way to re-mount this? The threads could be easily cut, but I don’t know if the holes in the skin are too fragile to re-use. If so , is there another accepted method to attach it to a supportive substrate? The donor did not have any information on the preservation technique. I have not yet tested it for arsenic. Thanks all.<o:p></o:p></span></font></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><font size=1 color="#2c6822" face="Californian FB"><span style='font-size:9.0pt;font-family:"Californian FB","serif";color:#2C6822;font-weight:bold'>Patricia J.
