I get the kids some sort of art supplies every Christmas. They're 13 and 11 now and I'm running out of ideas. DD is especially into drawing and colouring, but not painting. They're loving a big set of alcohol markers at the moment, and a big set of watercolour pencils DD got for school.
I'm not at all an artist myself so I don't really have a clue what else they'd enjoy. Any suggestions?
