Today I tried the Edgestitch foot, #10 on Bernina. That is pretty cool. You keep your eye on the guide in front, the needle goes right beside the paper. Single hole throat plate, no need to move the needle position from center.
Of course, I learn this tip after my entire quilt is done. If you have an Edgestitch foot, and most machines have one available, give it a try to see if you like it.
Thanks for the tip-- I think it came from Marti.
UPDATE--it was Cindy who suggested the foot she called the Stitch in the Ditch foot. Officially called Edgestitch foot, and is often used for topstitching where you would move the needle position a couple clicks.
