This is a very informal event.  People bring in what they no longer use or want, and then take what they do want or need from what another knitter has brought in.  Jodie Lucas of the Saturday Knitting Group will start helping to set things up at 9 AM, and the actual swapping will begin at 9:30 AM and go until 11:00 AM.  People can set out their own stuff where they think it fits.  It is recommended that yarns be separated according to fibers or weights. Not only yarn but also knitting books, needles and other knitting-related items may be brought in and swapped. Anything left over at the end of the day will be donated to charitable knitting groups.
