For ONE WEEK ONLY the Commercial Pattern Archive at the University of
Rhode Island is offering free online access! Login with the username
"guest" and the password "pattern".
http://www.uri.edu/library/special_collections/COPA/index.php COPA has about 48,000 vintage patterns (including the small scale pattern
piece images!) dating from 1868 - 2000 for you to enjoy. Now go and play!
It looks awesome, I wish I had more time to explore it!
