I am laughing because I am afraid to machine quilt because of wrinkles. Using the lap hoop I can smooth out the wrinkles as I go making my quilt nice and flat. Funny I never thought about adding some lack to the hoop, I kept it tight for years. This site teaches us all something new. I just purchased a floor hoop frame & love the idea of using it for the middle. Since I am moving to Fl next week I will be looking for ways to keep the weight & heat off of my lap!
