Our Sunraysia group had a workshop making Mobile Phone Holders... They are a great idea. You can put your phone in it with the charger plugged in and hang it off a hook or handle. They are meant to hang on the charger plugged into the wall.
Then at our retreat I made a large star fruit cushion. This size is to use upside down on your lap while you stitch. It supports your arms and is supposed to help relieve the pressure from your shoulders and neck.
