I just bought 50 mugs at Dollar Giant/Dollar Tree (similar to the attached photo). They are mugs with plastic handles and you can add your own paper inserts. Only $1.25 each and then we are going to make some fun labels that go with our theme as well as a party picture of me and my groom. They might not work as great thermal mugs, but they are a great price! We were originally going to order bubba mugs but as I spoke to a lot of my guests it didn't really sound like a lot of them were actually interested in using mugs. So why spend all that money on them just for a few people that would like them.
