This was my project this evening. I have two of the sweetest great-nephews so I made these mugs for them. They're going into a goodie basket with some flavored hot chocolate mixes and some cash. Both boys are old enough that they will appreciate having some extra spending money but I didn't want to just give them cash or another gift card this year.
I found the mugs at Walmart and used Armor Etch to put their initials on the side. Not very complicated at all.
The light on my work table made the glare beside the letters. I tried several different alphabets before realizing the Pooh Font would work best. Dealing with the curvature on the side of the mug was a little problem with some of the other fonts I tried.
