Wool Sweaters, Buttons and Zippers Needed

Posting this for my mother, who is doing a craft/recycling project: I am looking for wool sweaters (at least 50% wool). Can be women's, men's or kid's sweaters and it doesn't matter if they have shrunk in the washing machine or have some moth holes!! Also looking for buttons (preferably old or unusual ones that you might find in your mother or grandmother's button tin) and metal zippers. Please respond to nicko724693@yahoo.com. Thank you!
