Jaba, I personally don't celebrate any holidays and won't use holiday fabric. I feel like it would be somewhat of a waste if I swap 150 charms of fabric that I do like, for a bunch that I won't use. I would not try to change the "rules," but I would choose not to participate if I knew I would receive a bunch of fabrics that I just wouldn't use. I usually get a couple that aren't my taste in each swap (non-holiday), but that's different. I will use those in a charity quilt and move on. BUT, obvious holiday fabrics would probably go to trash or Goodwill.
