My guild rents a large beach house each year. There are 20-25 of us and around 10 bedrooms so we double up, 2 to a bed.
We have a lot of sewing space, we move the houses tables and bring in our sewing tables and set up. We are each responsible for one meal for the weekend and the cost of the rental is usually around $150 each. We go for a 4 day weekend during the winter months as the rates are lower then.
We sew our own projects but have one community project that we all work on at some point during the weekend for one of our charities.
It's always a fun weekend.
