Usually when i tie a quilt- i do it by the birthing method (Eleanor Burns of Quilt in a Day) where you lay the top and backing facing each other ,
with batting beneath. i pin and sew all the way around but leave an opening to turn right side out. then turn and slip stitch the opening closed.
then it tie. how far apart depends on batting instructions and the blocks.
good luck. this is the easiest way to finish a quilt in a hurry.
