I think I know what site you are asking about, but I don't have access to any of my bookmarks just yet.

However, it seems that I remember reading a year or so ago in the Copyright Forum here that some lace patterns are actually copyrighted. 

I also seem to remember there being a link to a site that has old lace patterns that are not copyrighted any longer and I think some of the merchants here use those.

Anyway, ask in the copyright forum too. Maybe someone there will have a better memory than I do and will be able to provide you with a link to such a site.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
