The chair finally did it and knocked me out during last weeks class. I had trouble piecing the pieces back together because the lineup marks I made didn't line up. Weirdly enough they matched the original marks and the original pieces fit together perfectly. Argh! I guess it was because the old fabric was stretched out pretty badly. So last Thursday I only accomplished to pin the back and front pieces for the backrest together. If I'd been a contestant on Project Runway Heidi Klum would have sent me packing with her You're out! Auf Wiedersehen! But I had my trusty Tim Gunn (aka our upholstery instructor) at my side that kept telling me to make it work...So there is hope for the next round.
