I love everyone's ideas. Here are my additions to the list:
I would travel to all the places I have dreamed of (mostly in Europe) and shop for fabrics, take cooking classes, and build a dream house in every place that I fell in love with. And each house would have a dream kitchen and a dream quilting studio with views.
I would also buy my Quilt Island.
My husband would get his dream garage so he can tinker and build engines to his hearts delight.
I'd give my kids money to get their own dream homes wherever they'd like.
And yes, DH and I would never work again for other people.
