Once the pattern pieces have been cut and laid in place, I simply went around all the joint, pulling fabric somewhat snug, and stapled the pieces together using a heavy duty office stapler. (High tech huh?) Then I sewed all the fabic pieces together on the inward (seat cover) side - trying to keep
I cut one long piece of fabric the width of the widest part of the seat and the length measured from the very back bottom of the seat all the way to the very front bottom. I then cut two piece for each side, one is horizontal to match the seat side and one is verticle to match the back rest.
