Project complete!
I ended up using 16 ga. fencing wire. Cheap yet sturdy and easy to work with. I had some left over "pet proof" screening (it wasn't
) so also incorporated that into my design. Should accomplish 2 things....1) it will hold a shallow layer of fir bark while my Catts. get established and 2) it's porous enough for new roots to get through.
Was able to make 13, 10" x 10" baskets out of 2 batches of the white cedar wood pieces I bought. Total cost came to a hair over $5/basket plus about 5 min/basket to assemble.
Think it will be well worth it. It was a good summer project while I was away from my collection. I've managed to collect 23 new "friends" over the summer so looking forward to getting back at it when I get down to the Keys next weekend for the winter. Right now though it would be tough to leave New Hampshire. 72 degrees, bright sun, zero bugs and spectacular foliage but all that will change soon in the blink of an eye.
Picture is of a Potinara I bought a few years ago that was mounted like this and is thriving so that was my inspiration to get all my smaller leaved Catts. off the benches and up in the air!
