If you are making these for your wedding or another event where you need to make a lot of these, this tutorial should help you make as many of these as you need, in the shortest period of time.
If you only need to make a few, skip ahead to Step 1 and scroll down to Semi automated. You can easily make a small amount of these quickly enough by just using a hand drill or Dremel.
Important things to consider before making these- timing and planting:
How soon before your event do you need to start? Well, I recommend hollowing out all the corks early on. You can do this at any point, the earlier the better. Corks, hollow or not, aren’t going to dry out or go bad.
