The cushion is constructed in the wanted number of squares.
Bigger cushions can with advantage be constructed with 9 or 12 squares, so that the filling will "wander" as little as possible.
The hardness/softness is set by the choice of filling and quantity.
The cushion has an internal seam with a minimum of 8 stitches per 2 cm, which makes the sewing down- and feather proof.
This construction is primarily suitable for back- and arm cushions and particularly for bigger back cushions.
The cushion is easy to form as you wish.
For instance, the back cushion can be produced with extra filling in the lower channels in order to give optimum support to the arch.
The comfort of the cushion is varied by the choice and quantity of the filling.
The squares keep the filling in place, so that it does not "wander" irregularly around in the cushion, which minimizes the need for working up the cushion.
