I have been wanting to build this island for years! Seriously. But we finally got to the point that we had some extra time, and no other projects were screaming at us! We decided to make our island 24in x 36 in. So 12in shorter than the original plan. This was an easy adjustment. We also added another shelf, which we love.
The only issue we had was the slat length. Almost all of the pictures I looked at showed that the aprons, and side supports weren't exactly lined up with the front or back of the 2x2 legs. I'm guessing they were put in the middle, but I couldn't find that info in the plan. So we decided to make our aprons and sides flush with the front of the 2x2 leg. This added about an 1in to the slat length. Sadly, I didn't figure this out till after we cut the slats. After re-cutting, things went smoothly! It was my first time using a Kreg Jig, and it was great. We had to use A LOT of spray paint to cover it, but I am so happy with the final result! It's not perfect, but it's homemade, sturdy, and I hope Ana-White would be proud!
