When I worked at a quilt store I developed 'fabric bolt elbow' ... gee, I could have called that workers comp! But then I loved being around the fabric every day.
The good thing that happened as a result of working there, physically, was that I had dislocated my shoulder about a year prior and could not reach behind my back to tie a bow, even after physical therapy. After about 4 months of working at the quilt shop, I got my mobility back!
