One more suggestion:
I do not know what to call it but how about the thing you use to keep track of items when you're in bed? Part of it is sewn with pockets and another part tucks under the bed so it will stay in place. The pocket part hangs down the side of the bed to hold the stuff.
My mind is going. Did someone suggest making a bag to hang off a walker? Or one to hang off a wheel chair? I've seen rather elaborate ones that functioned like purses.
I am keeping track of this thread too. Great ideas. Thanks.
