The donor for the below has been a leather couch cushion, in very good shape, given to me years ago by a neighbor, it's nearly exactly what was needed.

I had tu unsew it all to do my patron, and with the help of Sabrina, my colleague from the "design vêtement" workshop, made a very square 23 x 23 cm and about 70 cm long below. The front end as already the Velcro tape sewed , it needs a small patch of leather on the other end to finish the tube, and somme Velcro tape too.
