We have men in our guild. In fact, one of them has the fanciest long arm computer driven quilting "machine" I've ever seen. (he does wonderful work!) The other man is a retired doctor. I have only been in our group for less than a year but have found them to be welcoming and friendly. They offer classes, too, from quilt pros from out of our area which is a real plus.
The most important thing is to try to get involved in the activities. Don't wait to be asked--volunteer for the Opportunity Quilt or to make Comfort Quilts or whatever.
(And if "your" quilt is not a good experience, find a few friends and start your own---get together and quilt! ----plus you always have all of us online!!!)
