If you have a Pottery Barn anywhere chair that needs to be stuffed, there are a few things you'll need to do. First, remove the old stuffing from the chair. This can be done by carefully cutting it out with a knife or by ripping it out with your hands. Once the old stuffing is removed, measure the new piece of fabric that you'll need to stuff the chair. Cut this fabric to size and then begin stuffing the chair with it, using your hands or a spoon to push it into all of the nooks and crannies. Once the chair is stuffed, sew up the opening where you inserted the fabric and voila - your anywhere chair is good as new!
