This is a great museum. They have a pretty radical operations plan: there is no permanent collection of works on display. Quilts are rotated between display and archive regularly; if you return in a few months, every exhibit will have changed. That said, it's all quilts all of the time, and if you don't have a background in folk art, women's studies, or textile art, you won't be in your element. Also, be sure to catch the guided tour; it's difficult subject matter to really appreciate without help. On the other hand, everything about the place is first rate, including the guided tours (included with your admission--call ahead for times). Further, they have added some diversity in how they structure the exhibits now, dedicating about a third of the space to quilts as fine art (though, like everything, this is subject to change--this is probably the most flexible museum I've ever seen).
Bottom line: if you're interested in this sort of thing AT ALL, it's worth coming to Lincoln from practically anywhere in the country. If you don't see the point and don't particularly want to (and there is no shame in this), this will not be for you. Case in point: I'm a folklorist and an art fan, so I dug it. My girlfriend (at the time), though she does knit profusely, isn't a quilt fan and isn't into art; it wasn't one of her favorite dates. I'll reiterate again, though, that the guides really do a good job, this is a remarkable (mostly) American collection by any standard, and someone with an open mind might be surprised.
