When my daughter was younger she always tagged along in the shop. One summer she got into a birdhouse building frenzy. I was hard pressed to come up with some innovative ideas but here are two that are still on the property and have had several avian families.
It was fun to watch the creative juices flow after I made some initial suggestions and she started comnig up with her own ideas.
Toilet bowl floats, tea pots,
coffee pots old lanterns,hub caps, coconuts, kitchen canisters, she had a ball and sold out at the Saturday Markets.
