Rat Tail + Paws

Hello! I generally only deal in bones and the occasional bug, but I found a dead rat recently and would like to preserve its whole paws and tail.

A cursory look into this has given me a general to-do list of soaking in isopropyl alcohol (currently doing that, since the rest of the bones are clean enough to no longer need soaking), then drying either by covering in borax or by rubbing them down with salt+borax repeatedly.

Basically: is that right or no? What is the easiest and most effective way to dry these pieces for later reassembly? Am I on the right track?

Thank you!
