Drill 2 holes, 1.5 cm in diameter in each of the battens. Drill the first hole 10 cm in from one end (this will become the top) and the second 3 cm from the other end (and this will be the bottom).
Place your four battens on the ground and thread one of your dowel rods through all four at the top end. Then thread the other two rods through the bottom holes.
Fold the fabric in half and stitch together making a loop.
Put the whole thing inside the fabric and open up the tipi frame making sure that the middle seam of the fabric is on the floor side.
And you’re done! Just dress with cushions and blankets.
