I have a design for a quilting frame made from 2 x 4's. It stands on the floor and is easily setup. You go to the hardware store and get the brackets to make 2 saw horses, 2 x 4's, some c-hooks (eyehooks without the circle closed).
My mom has borrowed my plans but I will get them back on Monday and post the pic here. I sold my longarm so will be going back to hand quilting with one of these.
