The one I belong to is $15 a year, we have work shops once a year at a members house which is free. If we do have a teacher/designer come we use the due money and sometimes we need to pay extra out of our pockets it just depends on what the charge is to come. Bus trips we pay for ourselves to quilt shows out of the area. Yet our meeting place at a church only charges us $100. a year.
There is another Guild a little south of me in our area that has 1 a month meeting but a workshop every Monday. I believe their dues are $20 a year and $5 for the Monday workshop but it's from what I understand is not really a workshop as you bring whatever you are working on and work on it, bring a dish to pass around for lunch and seems to me more like a get together. I have thought of joining this one but not going to the workshops Mondays.
I'm thinking the dues charged for most Guilds are due to what the place they have to rent to meet.
But to be turned down because of your beliefs is something else and I would just make my own group and have those turned down join...I bet it would be a fun group if you did that!!!
