How to Sew a Curved Bay Window Seat Cushion
Bay window seat cushions come in a variety of shapes and styles, but the most popular is the curved bay window seat cushion. These kinds of cushions fit neatly into the space created by the bay window seat. They can also be easily secured into the seat, unlike the more rectangular kinds of window seat cushions that may stick out over the edge or even end up with part of the cushion sticking into the air.
A curved bay window seat cushion can be bought from local home furnishing stores, but they can also be made, quite quickly and simply, at home. Making them yourself means that you have a wider range of options for the material and color of your cushion. You also feel a great sense of pride at having made your own home furnishings: a traditional craft that can save your money and time.
Step 1 - Plan Your Cushion
Decide how thick you want your cushion to be. Measure the space left between the bay window seat and the window itself. You will need enough cushion stuffing to fill the space. You can buy foam filling and pillow inserts, but you can also add other stuffing to make the cushion extra comfortable. When sewing, remember that fabric for cushions comes in certain lengths measured by the yard, so make sure that you have enough fabric to do the job.
Fabric is typically placed on "bolts", which doubles over the material, so when you cut through a fabric bolt, you are cutting two pieces at the same time.
Step 2 - Make a Pattern
Make or use a cushion pattern. Making a curvy bay window seat cushion is simple: you will need a round or crescent shaped object to draw around, and you will also need to make this shape slightly larger than you want the cushion to be (in order to have material for the seams).
Step 3 - Use the Pattern
Put the paper down on the material, and pin against the fabric. Cut around the pattern until you have the shape you wanted. You can either fold the material in half to get two sides, or you can cut two pieces separately, depending upon the thickness of the fabric.
Step 4 - Sew the Cushion
Turn the fabric so that the pattern is "inside", then pin the pieces together. Put a small piece of the cord along the edge, and pin this into position also. Sew a small seam around the edge of the curved bay window seat cushion, leaving a small gap at the top.
Your cord should form an "edging"; if this has not happened, unpick the seam and start again.
Step 5 - Finishing Touches
Turn the fabric the right way round (so that the pattern is now facing you). Stuff the cushion with the pillow insert and stuffing. Sew the remaining seam by hand. When sewing this final seam, you can add a zipper so you can change the cushion cover when desired.
