Found this when looking for something else, just as you do.

It seems such a good idea as well, catalogue properly all quilts that it can, together with details of the quilter and where it is currently housed.

Not sure I can say much more as a whole waft of the website is about copyright – I’m not even sure if I should be mentioning at all.
Shame as I was really sold on the whole concept.
