Why don't you cut it up into several individuals then mount them all onto a big board made of cedar fencing?

I attached a mature shield to the front of a large half basket using a large piece of plastic mesh from a grapefruit or onion bag and a bit of panty hose. I used twist'ems and string to secure the net cradle to the basket. It looked pretty awful but a new shield frond grew over the mesh and I was able to remove the ties and string as soon as the roots grew through to the moss beneath. It is hot and humid here and I would hate to actually pierce anything I didn't have to.
