THE PHRONTISTERY and it's a wonderful resource site if you're not as knowledgeable about fabrics as you'd like to be. It doesn't tell you how to launder fabrics but I was able to find out the cloth name I couldn't remember was Osnaburg and it's a cotton not linen cloth. So I learned what I needed to know. Just look under the glossary for Fabric and Cloth. It also has tons of links to lots of other things you might like to know about in more categories than I can list here. It's definitely a site worth checking out.
