We grow a lot of herbs in pots on our deck. This year we grew chives, green onions, thyme, rosemary, oregano, basil, and sage. We had a bountiful crop this fall so we decided to make four gifts sets to give away. I made trays out of some 5/4 walnut, maple, and two from cherry. I milled the pieces and then cut them to size. I used a Forstner bit to drill out the bulk of the material. I then made a template out of some hardboard to make the trays consistent. I routed out the rest of the material so the bottles were loose, but not too loose. A little sanding and a few coats of amber shellac, and they are ready to give away.
This is a chunk of carved metal put in a soldering iron. Takes a few minutes to heat up but it works pretty well.

All the blanks milled up and cut to size. 
These are the jars that I will be putting the herbs in.
