We used high-density foam for our seat pad with a 5cm (2in) depth.
Use a 1.5cm (!⁄"in) seam allowance.
MAKING THE CUSHION PATTERN
To ensure your cushion fits your own chair exactly, you’ll need to begin by making a paper pattern.
Step one Take some newspaper and lay it over your chair seat to make a pattern. Draw all the way around the edge of the chair in pencil and mark where the ties will go either side of the back uprights of the chair.
Step two Add a 1.5cm (!⁄"in) seam allowance all the way around your chair pattern then cut it out along this line.
Step one Cut out the main fabric into the following pieces:
Top and bottom: Two pieces using your pattern. Transfer the tie positions from the pattern to one piece which will be used for the cushion bottom.
Gusset: For the length, measure around your cushion pattern and add 1.5cm (!⁄"in) either end for a seam allowance. For the width, measure the depth of your foam plus 1.5cm (!⁄"in) either side for a seam allowance.
Step two Cut the contrast fabric into the following pieces:
Piping strips: Cut 4cm (1!⁄"in) strips to fit twice around the edge of your cushion pattern, plus add around 15cm (6in) extra for joining the seam allowances.
Step three You can have the foam cut to size if you give your supplier the pattern or you can cut it yourself. We bought a square piece online then drew around the pattern and cut it out using a knife. Remember you’ll need to use the pattern without the seam allowances so it fits the chair and cover exactly.
ATTACHING THE TIES
Step one Cut the cotton tape into four pieces for the ties, each measuring 40cm (16in) long. Step two Place two lengths of tape on top of each other then pin them on one of the tie position marks on the cushion bottom piece with right sides (RS) together and matching raw edges. Tack into place.
Step three Pin then tack the other pair of ties on top of the other tie positioning mark in the same way.
MAKING THE COVERED PIPING
Step one Take two of the piping strips and place them right sides (RS) together at right angles and stitch together diagonally. Trim the seam, open out and press.
Step two Join all the strips together in the same way to make one long strip.
Step three Fold the joined piping strip wrong sides (WS) together around the piping cord and stitch the raw edges just 1cm (!⁄"in) from the edge so that these stitches won’t show later on.
Step four Take the cushion top fabric and, starting in the centre of the back, tack the covered piping cord all the way around the edge. Make sure you line up the raw edges and clip the piping strip at corners or tight curves so it fits neatly. Trim the end so it overlaps the start by 5cm (2in).
Step five Trim and join the two short ends of the fabric to fit exactly together. Splice the cord by removing half the strands from each end then wind them together for a neat join. Tack the joined piping strip around the cord and to the cushion top fabric.
Step six Repeat this whole process to attach covered piping all the way around the edge of the cushion bottom fabric.
MAKING THE OPENING
Step one We have made an opening in the back of the seat pad to insert the foam. This is then slip stitched closed once the seat pad is complete and the foam inserted as this is the simplest method. If you prefer, you can add a zip or press fasteners to hold the opening closed instead.
Step two Stitch the piping in place just across where you want the back opening to be. Use a zip foot so you can get as close to the piping as possible for neat finish. You will stitch over the ties at the same time to hold them in place beneath the piping.
ATTACHING THE GUSSET
Step one Starting in the centre of the back of the cushion bottom, pin the gusset piece all the way around with RS together to check it’s the correct length, then join and trim (if necessary) the two short ends so that it fits around it exactly.
Step two With RS together, stitch the gusset to the cushion bottom back either side of the back opening where you have already stitched the piping in place. Again, use a zip foot and stitch as close to the piping as possible.
Step three Turn the unstitched section of the gusset for the back opening under by 1.5cm (#⁄"in) to the WS and tack it into place. Having this edge tacked down to hold it together will help when you slip stitch it later on.
STITCHING THE FRONT IN PLACE
Step one Place the front of the seat pad cover RS together with the other raw edge of the gusset, making sure you place it so it matches up exactly with the cushion back shape.
Step two Sew the cushion front close to the edge of the piping all the way around.
Step three Turn your cover RS out and press. Step four Put your foam inside your cushion cover and slip stitch the opening closed. Remove the tacking stitches to complete.
