The PVC quilting frame plans from TumbledRose.com and PVCPlans.com are examples of free PVC quilting frame plans. Both sites have links to free PVC quilt frame plans with step by step instructions. Both sites also list links to other do it yourself PVC projects such as PVC chairs and racks.
To make a PVC quilt frame, connect four 19.5-inch PVC pipes together with T connectors to form a square. Next, attach a 40-inch PVC pipe into each side to make a crossbar and repeat. Finish by placing end caps onto each PVC pipe for stability and a raised angle for easier quilting.
