do you wear glasses?
I do, and a hearing aid... and I have spinal cysts and degenerative disc disease that makes prolonged walking/standing excruciating... I have a walker with wheels and a SEAT (available at your local walmart/rite aid/cvs etc for reasonable prices).... and you can get a wheel chair for $99 - a fold up kind - you don't have to have a 'regular' wheel chair...
you are injured and temporarily disabled - why not use the chair or walker?
If your hearing fails are you going to be one of those people who refuse to wear a hearing aid? - I LOVE mine! I've worn glasses since grade school....
Go to the quilt show, use any aids that you need, ENJOY yourself and DON'T APOLOGIZE...
geez, don't make me come over there...
