I kept forgetting to take pictures and the ones I did take I kept forgetting to post so before I forget here are some pics, they were all taken on my phone.
After the coats of sealent before I did the background and branches
After the Great stuff foam cured and I carved it up (stuff on background is some moss I had to figure out a better way for it to stick after this though cause none of it stayed very well haha)
I also made a tree hide by wrapping PVC in was paper and then spraying great stuff over that, slid off quite nicely, though because I got too eager and took the pvc out befor the foam finished curing it expanded some and the wax paper is now stuck in there.
After decorating and sealing everything a few times
In this tree I created a top area so the snake can hang out up there, The cloth part is fabric wrapped around screen so I can remove it and clean it if i need to, there is a solid part underneath to keep it supported. Not sure how it will work out but we will see.
