Thanks xenxes, I have seen the squidoo item. Seems the construction is easy enough.
Thanks, mistergreen, but I already have the bamboo. Sure is a good idea about the PVC, though. No worries about it leaking! A little creative painting and it would look like bamboo, too.
There are plenty of clear water sealer options out there. Make a trip to the local hardware store.
It should be ok if it leaks a little as long as the leaked water return to the same source.
