quilting or tacking for me depends on what I want from the finished quilt. If I want a quilt that is soft, warm and great for cuddling, then I tack or tie. But if I am looking to finish a quilt with a refined and artsy look, then it will be quilted. The amount of quilting done depends on fabrics used and the pattern. I don't like too much quilting because it makes the quilt flatter and much stiffer and not so cuddle friendly.
