I stick pins in my backing into my cutting board (cardboard) and stretch it across and pin the other side. Then I lay my batting over that and stick pins in it. Then lay on my quilt and stick it down at the first edge and stretch it slightly and stick pins in the other edge. I baste with safety pins every four or five inches both ways. When I have finished what fits on the table, I pull out the stuck pins and move the whole thing up. Again stick ins in the backing at the new position, batting and quilt stretching each as you go. I do fmq with this method and do not have wrinkles on the back or front. Hope you understand what I have said.
