I wound up getting foam to replace the cotton padding.
I choose this as you could cut it to fit. I had to cut two separate pieces.
I used fabric glue to glue the foam to the board. I got to this point in the project and the project was stalled for several weeks as I could not find the staple gun. Hubby had thoughtfully brought it up to the house for me from his shop, but then he could remember where he had put it in the garage. The staple gun was eventually found and the project continued..........................
I found this fabric remnant on sale at Wal-mart so I went ahead and used it instead of buying an extra pillowcase.
Getting ready to staple it.
I used this chair in the bedroom till I got the other one finished. It has been restored to the dining room. I think it goes better with the wallpaper.
