To make the horsehair padding it will be necessary to prepare the support straps
Create a path and sew with stitches backwards, separating the stitches by about 7/8 cm.
The legaccioli will act as a support for the horsehair and are used to keep them in position and to maintain the shape of the padding.
It is important to evaluate well the compactness of the hair that must be greater along the perimeter to allow the upholstery to keep its shape over time.
