My LYS got some of these in before Christmas. They were hand thrown pottery and very pretty. Pretty pricey as well if I remember correctly.
I keep my yarn in the bag I carry around with me everywhere I go!
I think my cat would have fun playing with any yarn she could get her paws on.
I came home one time from a long weekend away to find a wild yarn trail all over the living and dining room where she'd gotten into a ball and literally had a ball of fun with it!!!
