Do you have livestock ideas in mind?
Hey look here is the 18" X 18" Forest Floor kit design.
I closed down the sales thread that I had for that, but I can still offer deals for that kit for inquiries via TPT.
It will probably stay empty for awhile, I am running out of space here.
So I might see if my mom wants to grow orchids in it... not sure how that will work, but she isn't doing so well with them on the porch or office desk. lol
