Loved the article! Everything about it!
I was a little disappointed when my husband told me he just was not up to building the brick herb spiral that I'd asked for, so this article gives me an excellent alternative. I can easily get the pallets from our local waste management center. Thanks also for the update photos. I don't think I'll have any problems getting my hubby to help me with this project.
I'll send photos when we get it up and going.

Jeanne - Be sure you try to find some "furniture" pallets as they already have the little boxes built in the pallet. I love mine!

It's funny, because I planted 14 plants in those little boxes and all but 1 plant is still alive over a year later! I really anticipated replanted the herbs every year, but that has not been necessary. Amazing how they can grow with so little root room. Obviously they must be a bit invasive to be so tough!

I would love to see photos of when you build yours! Please do post some pictures.
