Revamp your outdoor space by making deep seating patio cushions, an achievable project for anybody with basic sewing skills. It only requires that you measure and cut out three pattern pieces and sew a few straight seams, and also you’re able to complete the cushions in a matter of hours. Making custom cushions is much less expensive than buying them, and you’ll have a huge selection of fabric options to select from. Use firm-density upholstery foam to get a seat cushion or soft-density foam to get a rear cushion; preferably, purchase deep seating cushion forms that fit your chairs.
Assess the width and depth of the seat or the rear of the seat for which you’re making the cushion.
Mark a rectangle on 5-inch upholstery foam matching the dimensions of the chair seat or back. Use the present straight edges of the foam just as two of the pillow sides, if at all possible. Cut out the foam along the marked lines using a serrated knife. You may also ask the personnel at the upholstery store to reduce the foam to size for you. Instead, purchase a deep seating cushion kind that suits the seat.
Mark and cut out two rectangles of upholstery fabric 1 inch more and one inch wider than the seat or back of the seat.
Mark and cut out a 6-inch deep rectangle of fabric with a length equivalent to the perimeter of the seat or rear of the seat — two times the length and 2 times the width — and one inch. This is actually the boxing strip.
Fold the boxing strip in half across its width using the right-sides facing and also the brief edges aligned. Place pins along the short edges. Sew the short edges together, leaving a 1/2-inch seam allowance. Press the seam open.
Pin one side of this boxing strip — now sewn into a loop — around the perimeter of one of this fabric rectangles, with the right-sides facing. Sew the boxing strip to the rectangle around the whole perimeter, leaving a 1/2-inch seam allowance.
Pin the other side of this boxing strip around the outside of the other cloth rectangle using all the right-sides facing. Sew the boxing strip to the rectangle and three sides only, leaving the fourth side seam open.
Make 1/4-inch snips to the corners of this seams using scissors. Be careful not to cut too close to the stitching. Turn the pillow cover right-side out through the open seam.
Insert the upholstery foam or cushion kind into the cover through the seam.
Thread a needle and sew the open seam closed using a slip stitch.
