Repurposed Headboard: A True Flower Bed!

A Permanent Flower 'bed' for My Backyard

What are the dimensions of each piece and how much do you think each one weighs?

If you posted a picture of the pieces you found, we could instantly see what you have to work with.

Hi Isabelle,

Besides using it in your garden, had you thought it might be good enough to sell to someone on eBay etc.

You could use them on your bed - might have to make brackets to attach to your frame. They could be used as decoration in the flower garden and grow climbing flowers. Use as trellis. Kind of a funky artwork.

In the garden, trailing flowers like roses over them.

make a bench or porch swing

Folks, please read through the conversation thread first. Isabelle has already shared that she lives in an apartment without a yard, garden, or porch.

I would definitely paint it a beautiful color and stick it in the garden for decoration and for climbing vines.
