Hetty, that line is actually old telephone wire!! I had some lying around and stretched it between posts on the porch and it worked perfectly. We use it for hanging herbs, onions and garlic (and anything else that needs hangin'!)
tinpins: great info! And those are some fantastic looking garlics you've got there. Do you clean them before you hang them?
woofie: I don't snip any of the leaves. Anna, I do snip off any blooms that try to appear.
Arlene, I was careful to keep the debris out of the pool.
