We don't have a need to pin where I currently work but at past labs I have used flat pieces of foam, like the lids from cooler boxes that used to ship reagents that are temperature sensitive.  You can cut them to fit whatever container you are going to use to fix the specimen.  Place a few paper towels on the foam before you put the specimen down to pin - it will allow the formalin to get under the tissue.  Foam can be a bit crumbly, like cork, but since you are repurposing something that would have gone in the trash you can always throw them out after the specimen is fixed.
