I'm having trouble finding good hides for my BP. Shes 3ft long or so and refuses to use the largest snake hide from the local petstore. One of those hollowed out tree trunk halfs. I've got more shopping to do but I'd much rather makes things to spec myself.

Post your ideas for ways to make homemade hides, materials to use, ect.
Right now i'm using a box with an entrance hole cut into it
