In addition to fabrics etc of special interest to the Grandma- (not the MIL )consider color and texture. Another alternative which may be more appreciated is a lap quilt- one that can be easier washed, handled and less likely to get soiled- that way she can sit with it and enjoy it- you spend a great deal less time on it. A lap quilt would be preferable as most residents complain of being cold especially those who are memory impaired. Residents are encoouraged to not stay in ther rooms but to mingle so something she can take with her and show off to staff and other residents would be of special importance to her.
