I recently participated in an ATC mingle. Our theme was to use Purple Onion Designs stamps. I ended up making three ATC's for my mingle partner.... and, I made 5 for Michele (the wonderful owner of POD).
I hope that she enjoyed getting the "secret" ATC's from all of us who participated.
Many of these images were colored using brush markers on the stamps. Gives a soft, watercolored look. "Mona" was from a recycled reminder post card from my dentist. The tag on the "fleur" ATC is a clear tag by MM's. Flower Power also uses the MM's clear flowers, sequins, and bling.
