Big fat pens.

Rubber bands - wrap them around anything you have trouble keeping a grip on, toothbrush, razor, water bottle. Makes little stuff bigger around, gives everything a rubbery grip. And I get mine free off the newspaper.

(Plus, I can tell my water bottle from everyone else's, lol cogfog)

And sippy cups for big people. Plastic (not breaky) and good if you tend to have bad walking days too.
