I bought Marti's book today. It was at JoAnn's for 30% off. My queen quilt with sides to the floor (over sized queen) is ready to quilt. 1) I must practice FMQ-it has been a while 2) I needed a managable size.
Marti has several methods. One similar to described above you divide into thirds, quilt the middle, splice the batting, turn the quilt around and quilt what was to the left of the center (it was not under the machine harp so it was out of the way-no need to trim the batting), then the 3rd side you reattached the batting, then quilt.
This sounds perfect for my quilt. First is practice. I may use this technique on a table runner I am piecing just to see how it all fits together, then go for the quilt. Table runner is for me while the quilt is a gift and I want it to be special.
