I have a wonderful cutting/work unit that's 73"x 42" and is a perfect height for standing at. I have a Horn adjustable sewing chair plus an adjustable office chair so that should help with some of the height issues. I also use acrylic extension tables on my MegaQuilter and Designer 1 embroidery machines - at times. My worry is that my present sewing desk is too high and I end up with shoulder and back pain when doing a lot of sewing/embroidery etc. Thanks so much for your thoughts! Food for thought!
