About to start some wine stoppers, and I just noticed that Ruth Niles recommends recessing the stopper in the end of the wood to prevent gaps between the wood and stopper due to wood movement. I did not do this on the stoppers I made years ago, and since I gave them all away I don't know if there was a problem down the road. I have one left, kinda dorky so I didn't gift it, a very small one with no movement problem. Do you guys/gals recess the stoppers? Have you seen problems?
