My son wants me to make his son, my grandson, a train bed. I have til next spring, when the coming new addition will be ready for the crib and he'll be just shy of 3 and ready. Anybody got any good ideas or plans for such a thing. I know he wants something pretty decent, but I don't have a clue what to even look for. I've seen a few but they looked awful chincy. Thanx in advance.
