I learned of the most amazing link today! It's to the online Antique Pattern Library. http://www.antiquepatternlibrary.org/
I've collected old and antique knitting, tatting, quilting, crazy quilting, crochet, beadwork, you name it. Most of the patterns I have are from the '30's and newer, but these are older - in some cases much older. There are patterns here from the 1800's...for fans of Victorian needlework it doesn't get better than this.
All the pamphlets have been scanned into PDF format, so you'll need Acrobat Reader in order to view the patterns. I may just have to print out a bunch of these to feast my eyes on over lunch today.
