I know nothing

Mounting's not difficult.

I just recently mounted some orchids using some branches off of my grapefruit tree.

I tied the plant on with fishing line.

Here's a link to what Tolumnias look like growing in the wild and how they grow on thin branches:

Apparently the branches are covered with lichens and some debris from the nearby scrub. So you might wanna try mounting it onto a piece of a branch with some coconut fiber instead of moss and provide some humidity of at least 50%.

You can stick the branch with the Tolumnia mounted on it in a shallow tray with pebbles and make a little pseudo-bonsai scene out of it.
