If I want a special design on my quilt I use a stencil or trace around an object like a cookie cutter with a washout marker or an eraseable pencil. I then lay out the back, batting and top on my Ping Pong table and baste the whole thing together with safety pins. At home I quilt on one of two round floor hoops I have. Each is about 36" around. For pieced geometric designs I usually just echo quilt around the piecing.
