I saw that video several days ago and I was trying to decide on whether to get the one for charm squares or the one for the layer cake (OR BOTH). LOL Your tumblers didn't look like 5" but I couldn't tell just how big they were. I do have a lot of charm packs that I have ordered through the years so the 5" might be the best choice for me although the 10" would really make up quickly. What do you think? Dixie in AL
