Used about 12 2" pvc pipes. Tried 1 1/2 inch, but bowed way too much. Upright 2" pvc pipe slides over 3 ft long 1 1/2 " pvc pipe imbedded in cement in each 3 gal bucket. Made mistake of not filling buckets completely full of cement,so we had to drill holes in bucket sides for water to drain out.
American Girl doll cabana. 6 precut to 2 feet 1/2" PVC pipe and connectors. 2 yards your choice of fabric, hem the edges with the iron on hem stuff. We bought a small garland of the poms and attached with small safety pins. Total cost like $15.
