Let’s see... you’ve stretched a blanket between two chairs to make a tent for your kids to play in. You’ve pushed furniture together to make a fort. And you’ve cut holes in the sides of a refrigerator carton to make them a puppet theater. So, are you ready to build them the coolest play structure on the block?

If you can use a calculator, measure accurately, draw straight lines, and cut, glue and staple cardboard, you can construct a cardboard geodesic dome like the one in this picture in a couple of weekends. Whether you are a parent, grandparent, teacher, or youth group leader, Domebook can show you how.
