This weekend I saw my local community centre was offering free kite making classes. I think they were Afghanistan kites because I know Afghanistan kites are quite well known and we have some Afghanistan refugees in town. Unfortunately I didn't have time to go but from what I saw, the people seem to be having a good time.
Maybe you can even get your sons to draw something and stick it in the kite, I'm sure they'd be so happy to see that as well!!
