You can organize your own retreat with as many or as few people as you want. You need a place big enough for each person to have 4-6 feet of sewing space, space for designing, an ironing board. I have organized several retreats for as many as 25 ladies. Some places let you bring in crock pots, some places expect you to use their catering. Motels have community rooms that they will rent to you. Or maybe your church will let you use their space in the middle of the week and you all sleep at home. Lots of options. The most important rule is: HAVE FUN!!
