Hello! I hope this is not an imposition, but I was wondering if I could get a little direction on repairs. Even being pointed in a good direction for resources and materials would be helpful. I have some beautiful old tarot cards from the seventies which are a rare reprint. The backs of two of them got chewed by some small animal, and I wanted to try to repair them so that the cards' artwork do not get hole-y or torn. Is there a type of acid-free paper pulp putty or something that could be applied to build those sections back up? I am considering book tape but I don't want the edges of the tape to catch or get pulled up when the cards are shuffled. Sorry that I can't include a photo to clarify. Any ideas are greatly appreciated! Sorry if this ask is inappropriate! If so, just ignore!
Thanks for your question @tepid-bathwater. A standard way to repair paper edges and corners is to use Japanese paper and wheat paste (methyl cellulose). Here is an instructional video on one method for doing that repair.
If you don't want to go through that trouble, you might consider mylar encapsulation. Here is a site with an instructional video on encapsulation at the bottom of the page. Both of these processes are reversable.
For more information you might want to contact @conservethis on Tumblr. It's a good resource for conservation infomation on social media.
Good luck!
