Here are a few clever recycling ideas I've found in my neighborhood (click images to view larger).
This garden utilized old broken window panes, with the most wonderful shapes as backdrop for a small koi pond and fountain.
A miniature fairy garden was built using old wooden crates at different angles.
This old metal bedframe creates a whimsical garden room at my favorite local nursery. In the springtime they plant it up with friendly violas and white bacopa that cascades over the sides. The drawers are planted up with bright pansies, and a floormat was constructed at the base with Irish moss (groundcover), that spells out "Mary's room".
Last spring I created these skeleton key windchimes, with fishing string, beads, and crystals.
