I've largely left the upholstry technique for the cushions up to Aleta. Her idea was to make a pattern of the pieces from an old sheet, and tack glue them to the cushion for a fit check.
1) Put tack glue on the front bottom, and position pattern piece. 2) Position cushion on outline drawing, to get correct slope. 3) Tack glue side piece in position. 4) Tack glue seat face in position.
Corrections were made during the process, and Aleta made cuts here and there to allow pleats.
5) Removed pattern pieces. 6) Traced only vynl upholstry material, and cut out.
