I'm glad I'm not the only one who tacks (or ties) their quilts. I've tried machine stitching all the sandwiched layers of my quilt but I felt distracted by the machine stitching visibility. It was my first try at it and only a baby quilt at that. I still think I prefer a tacked quilt. Like Clem55, I do my tacking at the block corners and stagger the rows, too. And without enough room in my rooms, tacking seems to work out better for me anyway.
