We had recently acquired a pallet, and I knew I wanted to utilize it somehow outside. So I had dC hang it on the the shed's wall, add some eyelet screws and I took it from there. He did the majority of the work though!
First Fender and I planted the seeds in small terracotta pots, I wrapped twine around them, and then found that they were pretty easy to hung if I made a slip knot loop in the back!
To mark the pots I wrote on wine corks, with a little toothpick stuck in the bottom.
