So we put drops of food coloring on a plate, add a bit of water, and literally paint the cookies. Girlchild says they look like they've been colored with crayons. After they're painted and dry, then they get glazed and we're done.
But it took a long time.
And it was so worth it. A few doors down, a young couple with two small kids moved in day before yesterday, so I made up a plate and took them some cookies, too. Seemed the thing to do, because I doubt they'd had time to make any as they were still unpacking, and one simply must have cookies to leave out for Santa.
Merry Christmas and happy holidays to all.
