I run quilting retreats and go to two of my own that is just for fun. We do have "Needy Nellie" at the one that I call my vacation. I make an announcement at the beginning of the retreat.. "We are not a teaching retreat,this is for our enjoyment to relax and get our stuff done. If you are having trouble with something,you must wait til someone can help you for 5 mins and only 5 mins. They are here to do their work, not yours" The first time I made this announcement you could hear the sigh of relief from the room. It took care of the problem. Hope this helps
