For a long time, I just had the white wooden "O" hanging there. In it's former life, it was a wheel on a kitcschy decorative wheelbarrow. The type that would be at home beside a gnome and a lawn jockey. Not that I'd know...
Next, I spray painted the metal cranberry sifter I bought at a yard sale, um, 3 years ago. I tacked it up and had "OO".
When I saw metal letters at The Christmas Tree Shop for $2.99, I broke my own rule about having only recycled items in the Junk Garden. I bought an "M", spray painted it hot pink and hung it up. For weeks, Ebby was calling it the "Ooooom" garden.
Finally last week I found the motivation to finish up.
My final challenge was the "L". I wanted to have an upper case "L" though a lower case one would've been much easier (hello, fence picket or tree branch). Then, a breakthrough. Salvaged staircase spindle (bought last year for $5 at an antiques store) plus wire found on a beach walk = "L"! I gave it a fresh coat of white spray paint and hung it up on the fence.
