In most upholstery sewing that needs a cording we use a 5/32" welting that is covered with fabric. The fabric is cut 1 1/2" wide, usually up the roll. The welt fabric only needs to be cut on the bias if
- The fabric easily unravels. Cutting the cording fabric on the bias prevents it from unravelling.
- The fabric has small stripes, such as corduory or a pin strip. It is extremely difficult to exactly match the small stripes in a seam with welting. We cut the cording fabric on the bias so that the cording will have diagonal stripes, which help to Camouflage any slight misalignment of the stripes.
- On round cushions the welting fabric strips go around the turns better if it has been cut on the bias.
The welting can be sewn using any of several different methods
- The fabric can be sewn around the cording separately, and then sewn onto the cushion panels.
- The fabric strips and cording can be sewn onto the cushion panels at the same time.
- The fabric strips and cording can be sewn into the seam of the panels and the cushion boxing all at the same time. This takes a little more practice and skill to have it come out looking smooth and nice.
