My 1st guild experience was similar-it had HUGE membership.
Does this guild have a new member intro, try talking to members about what the guild offers, check out their library, etc. Our guild now announces visitors and has special people to welcome them, then intro them to others. My current guild I went on their retreat first so got to know members over 3-4 days before even going to a meeting-it was great. Visit several area guilds before joining if you can. I bet you have much you could share on techniques learned creating your fiber art. Discussing your dolls and how you came to do them could be a conversation starter. Don't give up, it takes time to develop friendships.
