I couldn't sit at the sewing machine or computer for about 2½ months after I broke my back in Feb. After having a procedure done the end of March, I could sit a little longer every day so I slowly got back into quilting. It took longer getting back to the computer because I didn't have the brains to know when to quit and go lay down to relieve the pain. This board is just plain addictive...face it, we're junkies.
