Arizona,you are sewing very nice
pillow cases !

I like to suggest to contact the National Foundation for Transplants,
link.They may have a list of children's hospitals that perform transplants.In The Duke Pediatric Blood and Marrow Transplant Family Support Program
link it says", "Welcome Bags.Upon admission to the unit, the Family Support Program team will distribute a welcome bag to families. This bag includes a pager, phone cards (donated by the Katie Swaney Foundation),
a brightly colored pillowcase, a colorful laundry bag, a quilt, a disposable camera and several other small items. This is the Family Support Program's way of saying welcome."
