I am quilting the last 3rd of my CS. I quilt mine in 3rds - just sandwich, then cut the side battings off. Quilt the middle, then use fusible interfacing to put one of the battings back on, then quilt that section, then do the last section. I do have a large harp (Brother PQ1500s), this procedure makes it so much easier to quilt. I hope to have it finished this week.
