I’m starting my business, and am looking for supplies so I don’t have to keep a swift and winder out on loan from my knitting guild forever.
Anyhow, I happened upon this site, and OMG they are CHEAP! You can get a regular ballwinder for 20.00, or an industrial one for 55.00. (The only other ballers I found that can do more than 4 oz were 130 and up. )
