I wondered, then, after they were shattered, if the cracks could pick up color. So I rolled them around in food coloring, and HEY LOOK! It worked!

Thanks for the great idea!!! I bet the color would be more brilliant if I'd let them sit longer, but this is after about two minutes. I didn't want the food coloring to dry and require scrubbing.

















But that's okay, because the mug I use is massive anyway, and the added bulk of yarn (even though it's not bulky yarn, makes holding the mug really, really difficult. But, lesson learned! Now I'm going to make a mug cozy for a human-sized mug.
