There's never a bad time for some shameless promotion. If you visit your local Barnes and Noble (or if you want to drive to visit one far away) and visit the bargain section, you will find a display of kits on sale for Christmas (or "the holidays" for those who are easily offended).
Amongst the piles of boxes you should find kits for making balsa gliders. Not those cheesy, styrofoam, poor-excuse-for-a-glider kind that most kids today have played with.
And here comes the promotion part... ready... I designed and illustrated the box cover! Honestly, I've been a designer/illustrator for over 30 years and I still get jazzed when I see my stuff in print.
So buy one or two or three for the kids in your life and tell them, "I know the guy who did this!" I don't get any royalties, but you'll have the audacious pleasure of boasting to your friends that you know someone minimally famous.
