The number of coil springs used will depend on the piece of furniture you are reupholstering. On the furniture frame, you should have marked reference points of where the springs were originally located. This provides a guide as you place the springs.
Begin by laying out the back row of springs over the layer webbing, centering them with the marks on the frame. Next, grab your 6-inch sewing needle and button twine for sewing the springs to the webbing.
While this is a tedious process, it is a crucial phase. Remember this support system provides all the structural support of your seat! Once you have successfully anchored your springs down to your webbing, by hand sewing them, you will do the ties on top of the springs. For this step, you will need to use either Ruby Italian Jute or Polyester Tying twine for giving your springs an 8-way tie.
