You guys have such cute ideas!!
I have a bird bath too. One odd thing is that the dogs have figured out that it has water in it and use it as a water dish... weird. Also have a Garden Angel (the wings fell off this winter - I forgot to bring it in)... so I need to cement those back on.
The other thing I have in my garden are metal things - like old tractor wheels and old milk cans and other odd old metal items I found in the woods on the back 40. Oh and I have an old metal gate (antique thing)!!
