Three of my favorite kids visited last Sunday, for our annual “make-a-Christmas-gift-for-Dad”-workshop. They all make a little painting. One each year. By the time they´re grown up, they´ll have filled a wall! 😉
This year one of the dads joined in. Very successfully I might add. He kept in the kitchen, making us Christmas-tacos (so he wouldn´t see what his kids were making). And afterwards he read aloud for all of us. Joy! 
The paintings themselves are 20×20 cm, (8×8 inches), and color-coded. One in blues, one in greens. That way, they´ll all fit together nicely, even as the kid grows and his expressions changes.
