I haven't had any responses on Freeycycle either. But I did find two yarn shops about an hour away in Florida. There is one near Daytona Beach, I'm hoping my Mother-in-law and I will have time to visit later this month. There's also one near my daughter's house in Columbia, SC. So maybe I'll get to try the plastic interchangeables before buying.
However, I may be too late to put this on my Christmas Wish List for my husband. I always jump to other websites using the pull down menu. When I got home from work this afternoon, and used the menu, there was a website listed for a Navajo Squash Blossom Necklace. I'll take a squash blossom necklace over knitting needles any day! Don't get me wrong, I love to knit, but after my husband and child is my love for Native American Jewelry, and that's genetic, I think.
