This is exactly why I quit the guild I belonged to. These women were cliquey and rude to newcomers. This wasn't the way I was taught so I moved on. The Show & Tell is great, but not if you aren't comfortable. Just my $.02 worth.
I now belong to a group of ladies that meet at the library once a month. There are about 15 of us. We are not a guild and there are no dues. Just a short lesson and Show & Tell. Everyone is friendly and we have a nice evening. Maybe you could start something like this.
