At the age of 77, I can tell you that should I get several blocks done in my own beloved crazy quilt, then can not finish them, I would want someone to finish what I had started.
These were probably made for a small lap quilt, since they are fancy and shows off the maker's ability to make pretty things. I think they were brought out when company came to show off, not used every day by 8 kids and pets. Looking at masses of old pictures that i'm going through to send to the younger generation, I can't say that I have seen any of the crazy quilts out on display when a lot of kids are in the pictures, but with a group of women, every fancy thing the hostess owns is on display to show off. Fancy tea sets, prettiest dress the hostess owned, fancy crazy quilt on a chair back, etc.
