The vendors had a witty little sign that said "Yes, you could make these, but will you?". I guess we saw that as a challenge.

Nick said to me, well we could make some bird baths!
We bought 4 table legs and 4 bowls.
This one is my favorite... how perfect is it!
And here are the finished bird baths:
