I've just set up a new Yahoo group for people with this aim.
"Not for beginners.
This is a group for quilters who are NOT interested in the quickest way to make a quilt but the very BEST way.
We are the sort of people who will unpick as many times as is necessary to get it right.
We seek excellence in design and execution of our craft by hand or machine. We might enter shows, we might not but we want to produce work of which we can be proud.
Join if this is your attitude, if not this is not the place for you."
