I want to try my hand at mounting some of my orchid keikis and recently bought some tree fern bark and cork bark online because I could not find any locally. I have some questions:

Does anyone know of a good local source for these items?

What is the best way to cut tree fern bark squares into smaller sizes? I don't want to destroy the squares and it seems it could be tricky.

What about cork bark? I was just going to try a little hand saw.

Any suggestions would be appreciated.

Thanks!
