Using "real" bark??

[flipperyflop]

So I've been toying with the idea of using real bark for my background, can I do this? or do i have to use cork bark?

I live by a river, and its all washed up on shore, I've been collecting bits and pieces when my family and I go for walks, nd I have enough now to cover the entire wall above the water line,. I've soaked and baked..but is it safe? anyone try this?

I have a huge chunk of poplar and it works great..Just get the real old groved out trunk area bark and it is very similar to cork bark then peel the back real good cause the grubs hide under that layer of cambium. once dried spray foam the inside and stick it to the back wall. The size of the bark i used would have cost well into the hundreds of dollars for cork.
