I've done a few "sets" by placing them in collections, but would enjoy seeing them in true sets, and I think it might attract customers. Single notecards don't seem to be a hot seller, but a set? Maybe it would work better than my collections have where, in the end, the customer has to diligently choose each of the designs.
My single concern is that writing notes doesn't seem quite the thing it once was before email. The internet has wiped out a lot of that personal touch.
