I have been to three of themn. It was organized by a group of ladies that run in shop in Southern Mn.Had a place renter on a lake in central Mn. Send out a list of classes and you decide what you want to take. They brought vans of fabric and anything that went with sewing, in case you needed needles or whatever.You brought your machines, sewed till you dropped and had your own bedroom which you shared with a friend , meals were all cooked for us. It was a three day retreat. The night before the last day we had a show an tell and someone would come in with a trunk show. Had a good time. You have to try it. I'm sure you will love it and want to go back again.
