This has been a lot of fun for us, so I thought I would share the idea. Miss G is studying about Native Americans, so I decided to make this tepee from Family Fun magazine(link will take you to directions). It cost us $33 to make. The most expensive item is the canvas ($20). It was pretty easy to make thanks to my husband cutting the pipes for me to make my 10 ft. pipes into 8 ft. The tepee is also easy to put up or take down. One note of caution, the tepee is more sturdy on a carpet or grass and little ones can knock it over. Ours fell down twice due to excitement, but I do not think this would have happened outside and it is pretty easy to put back up. We are going to try to make a doll size tepee with the leftovers (1/4 the size of ours).
