If i raise my chair up so my elbows are at 90 degrees then i'm too high to reach the foot pedal. Also my legs aren't long enough to bend at the knee in most chairs unless i sit on the end (or slouch) and have no back support. I have short arms too which make it difficult to maneuver a quilt when machine quilting. I just do the best i can. Ok, I'll stop whining now!
