I just discovered a fantastic reference for researching vintage textiles.
Since I'm usually about 6 months behind new things I guess you already are aware, but just in case you don't....
I was searching for some history on Leedes Fabrics 300 Walnut Street Phila. 6, PA and ended up at Googles Internet Archive where Google have scanned old books.
I was excited.
There are a lot of books on textiles and I have to say they all look like great reading. If you have a reader of some sort it would be great to take these around and browse while waiting for the bus.
Check them out here: Google Internet Archive where I typed in the word 'Textiles'.
You can read these all for free! and hey there is not much in this world that's free.
Oh yeah except shipping from my website!!
