I'm almost afraid to post this. I belong to a quilt guild with 500 members. I also belong to 2 small quilt groups. Love all of them and have never notice unfriendly people. I used to belong to the American Sewing Guild but they were all about sewing clothes and I no longer do that. There are sewing guilds, knitting guilds, doll making guilds, quilt guilds, and just about any other guild that has to do with arts/crafts. Just google and see all the choices we have.
My guild acknowledges visitors at each meeting. Also, new members get to attend a special meeting each month that is just for members that have belonged to the guild for less than 1 year. They get a lecture each month from a teacher/book writer/talented guild member. They also form small groups during this year. That is how I found one of my small groups. The other I found from an ad in the paper about a new library worker hoping to form a quilt group.
