In this video we'll show you how to make a humped or arched cushion. This cushion involves creating a curved boxing that helps to reduce
and eliminate wrinkles that would otherwise be prominent with humped shapes. The type of cushion-making
technique in this video features a zipper on the underside — not in the boxing — and continuous boxing, instead of boxing that is seamed at each corner. After watching this video you too will see how easy and fun it is to make cushions for yourself and save
money!
