Ever realize after you've bought a book or patternthat you already have a copy of or you glance through and know there's no way you will ever do anything with it?  I think everyone does it now and then.  I have a whole crafts library sitting here taking up space so I am more than willing to share.  (We won't even discuss the stash of fabric that seems to be breeding like rabbits.  :)  But that's not for sale.
