sewing for a week

Ok! I figured out I cannot sew for 8 hours a day. My hands are swolen and hurt like he**. Its like instant arthritis. I feel like a wimp!!! I ve gotten a lot done tho... costuming for a childrens production is almost complete... just need to finish up another goose and make a little cape and hat for a mouse! Im going to sew for 4 hours today and split it up to see if my hands feel better.
