You can find all of our Dragon Boat Festival posts here.
At myweb3000 you can find a printable dragon boat with a short description of what is found on a dragon boat.
Mummyshymz also has a printable dragon boat along with a few homeschooling ideas done for the festival.

Ikat Bag, as always inspiring with patterns and tutorial for cardboard Narnia boats, that, again, could be converted to great dragon boats.
