Decorating Mugs & Plates With A Sharpie Marker

Based on Decorating Mugs & Plates With A Sharpie Marker by Miss Vicky Viola
I made these as Christmas/New Year present for two friends. I was really glad to find out that I had colored sharpies, and went crazy on the Snoopy jar, as you can see. ;) The colors were actually altered and made less bright after coming out of the oven, and I'm quite pleased with the resulting colors. I had to put both of these in the oven twice, at 350 degrees and for 30 minutes, before the colors wouldn't rub off easily, and I'm thinking it's because the cup and jar were porcelain (just a warning for others using porcelain).
