So-called Reupholstering a.k.a. Giving The Chair A New Skin
I took the seat off to see if it was worth rescuing, paying attention to the foam.
With all systems a-go, I went ahead and plotted on colour schemes. This is where hoarding random upholstery remnants and samples pay off. (In my opinion.)
There were curves and many pins involved. It is very 3-dimensional, I gave up on measuring.
I also basted the seams when too many pins got in the way... This was then lifted off to be machine-sewn and seams overlocked.
The bottom bit almost stopped me in my tracks. But that'll do. I imagine a proper slip cover would skirt the bottom of the seat.
By some fluke accident, the bottom flap got stuck on the velcro, making things look tidy on the outside.
Did I do that? Beginner's luck, maybe. Woven fabric can be forgiving when stretched on foam.
The seat was probably the fun bit, with no sewing but tools getting involved.
The ugly bottom will just be a secret between you and me.
