You will not be able to do any hand work while being an actual juror. However, if you do get selected, ask if you can work during breaks and if you are so unfortunate to be selected for a trial that requires being sequestered, do take work with you. You will be glad you have a distraction as you cannot watch TV except under group supervision. I stayed in my room hand quilting on baby quilt the time I was on a 1 1/2 week long trial.
