I must be in the minority. I overlap my Warm and Natural battings approx 1/4" and do a serpentine stitch. Yes it makes a slight bump in my quilts but not enough to fret over. No one's ever mentioned feeling it while sleeping under the quilts. I don't make quilts to submit for judging,. But if I did, I admit I would just butt the edges up like everyone else. My way is just easier for me and, admittedly, a habit.
