Keep your wrists from getting fatigued during a long day at the computer by making this pool noodle wrist rest. First mark where you want to cut the noodle. For the wrist rest shown, we made the height slightly less than half of the full noodle diameter. (You could cut the noodle exactly in half and make two equally sized wrist rests.)
