does your guild have nonprofit status with the IRS? They have very specific guidelines as to what constitutes a true nonprofit. Our guild went through the process a couple of years ago for the purpose of accepting donations for a charity project--lots of work to get done!
that being said, I don't think there is a criteria of having to gather and make charity quilts any set number of times or at a specific place. Obviously, the guild would need to be focused on some type of community service and not making profits. Perhaps what the guild needs to consider is changing up what you do for charity so that all want to be involved. We do meet several times a year to work on charitable items, plus members work at home and bring things in.
