What you need
3 yards (2.8 m) of ribbon
Start by measuring the chair from the floor at the front to the back of the seat, up the back and down to the floor.
Add around 5.5 inches (14 cm) to the length for hems. This will tell you how much fabric you need.
Measure the width of the seat to see how wide your piece has to be. Hem both long edges of the fabric and then iron flat.
Place the fabric on the chair and center it so its sits nicely at the front and back and pin it ready to hem.
Mark the back of the chair with the seat of the chair to see where the tie backs will be sewn on. You will need two tie backs on the front piece and two on the back piece, as shown in picture.
Sew the ribbon to the four marked spots for your tie back.
And you’re done!
