I LOVE creative reuse of materials in the garden (and anywhere, in fact) and I was blown away by this project I first saw on Pinterest.com. (BTW, you can follow me and my garden finds on PInterest, too)
This gardener used an old futon frame, hung on end, as an interesting garden gate. I have on older futon I am about to give away, but now I am thinking of doing something similar with it. The sleek modern lines of most futon frames work well for this type of arrangement. It might be a bit too modern for some gardens, but I am sure there are ways to paint and theme to fit in almost anywhere.
It is great to see such creative thinking and reuse of materials that might otherwise simply be thrown out.
