I'm going to a quilt retreat early in March. There are 24 of us. It's a regular retreat center. Each has their own room.
We have done it for 3 years. I don't do the walks, trips to the quilt shop, games, etc. We have 12 in each big room and I've come to like the ladies and look forward to seeing them. I just set up my stuff and sew for 3 days. Some gad about, cruise around to see what everyone is doing. Walk around talking. I just sit and sew. Try to really take advantage of not cleaning, cooking, or running around. I'm happy to just sit and sew. I precut my project. I come ready. Do what you want to achieve at your retreat. I don't do group projects. Although one time we made each other name badges before we got there. That was cute. I used a leftover crazy quilt block, cut down. Added some stuff and her name. Sometimes we bring a fat quarter to trade. One of the ladies gave a tutorial on folding and sewing a square so it was 3D and looked like a bow. A few times after that I saw several people had made whole quilts out of the bow squares. Utube it to see a video. Let me see if I can find the link.
