Three years ago, we printed off the names of the types of Garlic we had and had them laminated at Staples. They were cut apart and stapled onto 1×2 stakes. The last two years we simply printed off any new names on paper and then used transparent shipping tape to protect them from the elements and also stapled them to 1×2 stakes.
This is the result this year. The laminated signage is great, the transparent tape was illegible.
So before planting this year we went out with the entire list and laminated them and made some new signs.
