Question about how to sew horizontal indented line on sofa cushion.

[ky bob]

Hi, I am thinking about recovering my sofa and I want to know how to sew in the horizontal crease in the seat back cushions. Does anyone know how this is done ?
The picture enclosed shows the original cushion with the crease across the middle of the cushion.

Upholstery supply businesses sell a small round plastic rod in any length you want. It comes in 1/16,1/8, 1/4 inch diameter. sew a loop of cloth to the horizontal seam, insert the plastic rod then attach draw strings to the rod and pull the rod towards the back of the cushion and tie them off. That keeps the horizontal seam looking the way it does in your photo.

There are other ways to accomplish this task but this has worked for me. When you take apart the cushion in the photo, you'll be able to see how the manufacturer made that seam and you can copy their design.

Take it apart and reuse the parts/method to draw the new seam inward. If you wanted to change the look, you could use buttons that get tied down to create dimples.
