How kind of you to make this quilt for them.
It is something that is appreciated, not only by the family of the deceased, but by the staff involved and the other residents of the home. It's a nice warm touch at a difficult time for all.
They may have very specific requirements.
It's best to speak with your contact at the nursing home.
Here are some of the discussions that we had when I made the one in the link below.
Gurney size of course, will dictate the sizing, which they can measure for you.
Plus, how much drape is safe, so as not to cause problems when moving the gurney.
What are they using now? ... measure that and adjust to their requests.
Religious connotations may or may not be important to them.
Discuss colour.
They may have specific colours or depths of colour that they want ... or not want!
Laundering requirements will affect your choice of fabrics, batting, etc.
If it is their first "Passage Quilt" they may want it to be generic and for all ages.
If it is not their first, they may wish one more male oriented, or female, or child etc.
One Hospice that I know has an assortment, and tries to match the quilt to the person.
Eg. flowers for a gardener, a farm or country type for a farmer (yes, they even have a tractor quilt!),
teddy bear for a child, etc.
Here's a Passage Quilt that I made for our local Hospice.
