I cut the bottles with a tile saw. Cut the bottom off thin and then cut the top for the goblets. I 5-part hand sand the edges. I used a two part epoxy to glue together. I found out that it was not a food grade glue and could be toxic when wine or liquids mixed with it. I got one that was and it did not hold as well. Loves it!
