Oh, I meant to add that, at least for my parents, I'll include a booklet with photos of all the blocks and why they were included in the quilt.
An envelope on the back could be good too, not sure how much I can include on a patch.
I will probably put their names, birthdates, and who made it. Maybe names of the children and grandchildren as well.
The booklet will allow me lots of room for info.
