Sounds like you had a great time. I just got back from a retreat too. I can't believe how much I got done. And let me tell you, it was a tough weekend for my credit card. Having a quilt shop right there was waaaaay too handy. But I got some great fabric and ideas for a few projects.
And in July, five friends and I are going to Sisters for the outdoor quilt show there. We rent a house and spend a whole week sewing. We usually take some classes, but this year we all decided to just go to a few lectures and spend more time actually sewing. We rent the house from vacation rentals.com. The gal who owns it is so nice. She knows we go every other year and she doesn't rent the house out for quilt show week until after she hears from me whether we want it or not. Of course, every even numbered year, we want it.
If you have a chance to go to a retreat GO. They're a ball.
