Quite a while back, someone posted a tutorial complete with pictures on how to install a quilt sandwich on a Gracie quilting frame. I printed it and used it to successfully complete a quilt. Now I want to install another quilt on the frame and can't find the tutorial. Can someone lead me to this tutorial (I have searched and cannot find it!). Or clue me on what goes where on these confusing rollers. And forgive this aging brain!
