Here's yet another idea inspired by a trip to the local builders'
supply store.

I saw a bundle of old cedar roofing shakes and started to wonder
whether
they'd be useful as slabs for orchid mounts. The store gave me a few
to try
out, and I now have two divisions of an upward growing Onc. specimen
(I don't
know what species or cultivar) mounted on them with some "orchid
moss."

BTW, the idea I broached earlier about using nylon abrasive pads as
orchid mounts is getting a test with an Aer. citrata. So far, so
good.
