First you need to realize these will not be owned individually. They will all go into the wash frequently, and be stored on a shelf somewhere and given out as needed. It would be best to make them all uni-sex so that one of the men isn't forced to wear one that looks feminine just because it is the last one on the shelf when he needs one.
Make them ugly, or at least plain. If they are pretty they will be stolen by workers and visitors. Theft is actually why most quilts disappear very quickly in places like this. My local one actually begs people not to bring personal quilts to the facility for that reason.
Do not add pockets that the laundry workers will have to empty. They can't stop long enough to look for pockets they don't know exist, so the whole load of items will have shredded tissue all over them when they are removed from the washer. Debra in VA See my quilts at
