I would not use LQS fabric for the project. If these are used by folks in assisted living, they may not be cared for by the recipient and just be tossed in with the regualr laundry. Unless you are a quilter you have no idea the cost of fabric, so most would just consider it overpriced, and you are selling up against folks who used WM fabric. It is more of a utilitarian item than decor, so I suggest less expensive materails.
