LQS has a winter (January, not fun when we have to drive in the snow) quilt retreat. I have been going for 8 years. Big sewing/dining hall, cabins for sleeping and food provided. So we can sew to our heart contents and sleep if we want.
Plus a few friends have decided to have a small 'retreat' at one of the gals beach house. 4 of us went in the fall and 5 of us will be going next month :) We each are in charge of a meal of two. We try to visit the two shops in the area and might take ourselves out for dinner. Very casual, but fun.
