Materials: Grundtal Double Towel Rail
Description: I measured my fabric for my sling, adding a generous allowance on all sides for the casing and hems (1 inch in my case). I then hemmed the (short) sides of the rectangle (making sure the finished width matched the width of the rail) and then sewed the casings for the rails on the long sides. I then simply unscrewed the rails, slipped the sling on and…voila!
