If you handle the mugs prior to sending out. You could get that labeling machine and make the name tags. They don't fade and are water proof.
I painted our names on our Bubba mugs with nail polish. It has lasted 3 trips to TTR, sunscreen, chlorine, sand and all. Think this would be WAY too time consuming though for Jannet and your kids to do! Maybe there is some other type of acrylic out there? Kelly
I'm experimenting with several types of paint and labels, but haven't found one that will last in the caustic waters of the sexy pool... lol
