Assortment of fabric (I used old tapestries I already had)
Glue (I used Elmer's wood glue and hot glue gun)
Purchase six 1 x 2 x 8's at your local store. On each piece of wood, measure 1 foot down and in the center, drill a hole using a cordless drill. (They can also do this for you at the hardware store). This is for the jute that will hold it all together.
Arrange the pieces of wood in the "tepee position" and string rope through each hole.
Wrap the rope around multiple times to make sure it is secure. You'll definitely need an extra set of arms, but just gradually position the poles and as you add each one, string them all through with jute until they feel right for a tepee shape. When you are finished, wrap it around until it is secure.
Starting at the top, cut fabric into strips. Layer a few pieces and secure them with glue. This will be the top of the tepee.
Wrap fabric over, under, over, under. When one section is under and done, make sure the next section is tucked around the pole so that it's hidden. You can hot glue as you go and hide the wood.
Tip: Make sure you save your biggest pieces of fabric for the bottom… the gaps get larger (and the pieces get longer) as you go.
Alternative if you want to forgo the fabric and use a tarp: An alternative would be to take a simple drop cloth, drape it over and pinch it in place with a giant clip. You can have your kids paint the drop cloth before you drape it over the tepee.
