I was a Hospice employee (volunteer coordinator).
THANK YOU for offering to make lap robes for the patients. My first thought would be to remember if they're used in a nursing home, they will be washed in very hot water. I made lap robes out of double knit fabric.. amazing how many people still have some in their stash. That fabric lives forever! I did not use batting in those, just two layers of double knit. If they are used for someone in a wheel chair, you need to consider the wheels, etc. so they can't be too big. You might check with your local Hospice AND nursing home for size requirements, etc.
Another thing that was most useful was small pillows. The nurses said they were great for pressure points. Some as small as 6"x12" not stuffed too tightly were just the thing. Another good use for your smaller pieces of fabric. And the fun prints put a smile on the patients face.
Whatever you make will be most appreciated!
