I bought a very nice little white featherweight and didn't get any books with it and I feel so dumb because I can't get it to sew. I know it worked when I bought it but I put thread on the bobbin and try to bring it up and it won't come to the top. Does anyone know what i'm doing wrong? I guess I need to buy a book on ebay but i'm frustrated now, not when the auction ends and the instructions get here. Any suggestions? Thanks
