I have attended 1 retreat last year and am going again in April. We go to TN (and we're from NC) and stay a week with a quilt shop right next door. It costs about $287 for the week. We have a meeting before we go to discuss meals then we wait until we get there to do the shopping (usually costs about $20/prsn...and we have 6-8 people). On Wednesday we go out to lunch and shopping in Pigeon Forge to other quilt shops. It's so much fun!! We take UFO projects and usually the quilt shop will show us a little project to do.
It's nice to be able to not worry about anything for a week. Just sew till you drop....LOL
