Make a mark 6 inches from the floor.

Cut at this mark.
Pin the first panel to the top back panel of the chair. Edges should extend 1 inch beyond the chair. At the front edges of the chair, pin a 1-inch double fold.
Split the center of the fold (you only cut through one layer). This becomes your 1-inch seam allowance for the two pieces.
At the center top of the chair, smooth the fabric toward the deck of the chair. Pin seams. Shape around the arms, clipping as needed.
Allow the fabric to extend into the deck for 5 inches and at the arms 3 inches.
Fit the outside back from the center top and work outward, pinning as you go.
Fit the arms. Ease fabric around curves.
Measure the top of the cushion and add a 1-inch seam allowance. Cut two pieces of fabric this size. This is the top and bottom fabric.
Measure the depth of the cushion and add a 1-inch seam allowance. Cut four bands this wide and as long as each side of the cushion plus 1 inch.
Pin bands to the sides of the cushion top and bottom fabric.
Sew all pieces together at their pinned lines.
Insert bias or welting as usual and sew where you wish them to be in the finished cover.
