So first off, Jake took the old recessed lights out. *Note* if you're not familiar with electrical work, please call an electrician.
Then we got this gorgeous old barn beam from Jake's awesome uncle. It was cut to length and Jake predrilled the holes for the lights and bolts. I gave it a light sand, but I didn't want to take anything away from it.
Once the beam was up, it was the lights turn. We found a few tutorials via Pinterest about making your own lights from lamp repair kits, but then we found these! They were more expensive, but made it so much easier.
I took the mason jar lid, traced my circle, and used a drill bit to punch it out. Sorry I didn't get a better picture of that.
