I'd been decorating cookies for a couple of years...I always decorated at night after putting kiddo to bed. It never failed, I'd crawl into bed after a few hours of decorating with an aching back and tense shoulders.
One night, Mr. E walked into the kitchen as I was decorating and said, "why don't you raise up your work surface?"
Now when I decorate, I *always* raise up my cookie sheet.
Raise 'em up. No more hunching.
Thank you notes from your back can be addressed to Mr. E. ;)
