My niece's husband send the measurements of the chair and my dh made a cardboard replica of the back and seat so I made my pattern from that.
I had never sewn anything remotely like this before, so it took a few tries !
After my first attempt that I realized that I needed something, but wasn't sure what that something was until my niece just happened to send me a link to show me some owls she liked,
sewlittlefabric.blogspot/2011/03/0wl-softie-free-patterntutorial.html (I cannot get the link to work) While reading the instructions I discovered that the "something" I needed was a gusset! Had never heard of it. Kind of sounds like an old fashioned name for some kind of fancy lingerie ! Anyway that did the trick, and I would have never figured it out without Paula's help. Thank you! When my niece came for her latest visit, I didn't have it done, I sent the red & beige trial run to them to make sure it would fit and she brought it back, marked where the ties & belt would go. Gus used it as a play mat while he was here (he seems to like it) To make his mom happy I designed it so that the cushions would be secured by velcro, but she could remove them to wash the cover (I even remembered to prewash it)
