Brown chaise lounger is an unusual type of sofa with a reclining seat and back and a single arm that also acts as a back when a person is not in a reclined position.
Place the muslin over the seat of the cart so fabric drapes over the front edge to 2 inches above the top of the feet. Fabric should drape over the back and side edge in the same amount. Cut the fabric with scissors where it wraps around shortened back so that you can attach the fabric to the first muslin piece with a half-inch seam allowance. Fold and needle chair corner and trim along the bottom so the fabrics are an even 2 inches above the top of each leg of brown chaise lounger.
Sew the seams together. Eliminate your rounded areas with 3/8 inch cuts in the seam margins and cut the corners to remove excess fabric. Turn the lid straight and mount it on the trolley. Tuck the fabric onto the brown chaise lounger against the back joints as much as possible. Tighten fit with additional locking and sewing if you think it is too large in some places. Open the seams on the muslin furniture cover. Iron pieces. Place the muslin over the washed decorator fabric. Pin the muslin to the fabric and cut pieces with a scissors.
