Merry Christmas. :)
I'm planning on doing something today that I wimped out on last year. I've done my nails in alternating green and red, in colours approximating the traditional Holly leaf and berry colours, and I plan on going to my inlaws place for lunch, then to a larger gathering of more inlaws in the evening, in boy mode, with my nails like this.
I have approval from both my wife and son to do this, although my son preferred a lighter shade of green. I applied the red to one middle finger nail and the 2 greens to the nails either side of it and wore them like that for several hours yesterday while trying to choose which green to go with. When I put them against the shirts that I have to choose from, there was no contest as the lighter green simply didn't work with any of them.
If I survive the day, I plan to post a follow up tomorrow. :)
