I found a website that gives the simple quilt pattern used by a quilt guild for their dialysis center:
"Quick donation quilt"
www.stcroixquilters.com/Guild%sub-we
They also mention that the size needed is 45x70.
Do not use white fabrics.
Use 100% cotton or flannel.
Quilts should not be too bulky-please use a thin batting.
Use any pattern you like or the quick pattern below byJen Lacasse.
A picture is shown also.
Hope this helps with ideas!
