I have participated in 2 guilds in my life. I have never felt like an intruder in any of them. But then, I may be one of the few. I don't know where you live, but if you can find another Guild close by you might try them
When I moved back to my old home town, there was not a Guild. I ran an ad in the little free paper, and advertised for some quilting buddies, and started my own little group. We eventually started our own little Guild with a day meeting.
Most quilters are lovely people. Keep trying. So far as quilts go--any quilt is beautiful--even this nightmare I created at a class.
