I'm thinking about building a light box to use when marking larger swirl/floral patterns on some of my quilts. I can tape a section of a pantograph to the light box and then place a section of quilt top on it and with the help of Crayola Washable Markers trace the pattern I want. It will take a while to do it, but once I get the hand/arm movement down it should be better and faster. Light boxes can also be found at art supply stores and on Amazon. I have a small one, but would love one about 12x24" or more.
