I lay my cardboard sewing board on the table top fully opened out,.. Then I line up the backing on thereThen I and use straight pins to secure it at that line. Smooth out the backing as far as the table goes and pin there. lay on batting and smooth. Add quilt and line it up with backing and and pin it along the top with straight pins sticking into the cardboard mat. Then I pin this section fist width apart. Roll it up on something firm ( I use some old metal headers for wide with drapery rods. Then I unpin and move it up and resin as per first section and pin. Roll and keep going. I do this for fmq with a small Brother and don't seem to have trouble with tucks on the back. Hope this is clear enough for you to figure it out.
