The ultimate summer nap: Create a curl-up space with room for a double-size air mattress
Make 2 panels for the front flaps of the tipi and 2 panels to stitch together as the back of the tipi: Start by measuring out 2 lengths of your main/exterior fabric, each 46½ inches by 93 inches. Place these 2 lengths of fabric on top of each other and cut as shown to make 4 pieces, each 42½ inches at base width, 4 inches at top width, and 93 inches in height.
Front and back panels: Hem tops 1/2 inch and turn again 1/2 inch. Hem bottoms 1/2 inch and turn again 1/2 inch.
Back panels only: Stitch center back seams together to make 1 solid back panel.
