The thing that makes this board so great is that we all have our own opinions but respect the opinions of others. Some like puffy, soft quilts; some like flatter, closely quilted quilts. Each person is "right". I love hearing everyone's opinions and ideas, as it really helps me come up with better ideas for my own quilting.
How the quilt is going to be used also matters. For a show quilt, the quilter is showing her quilting skills as much as she's showing her piecing skills. For a much-loved, much-washed quilt, it needs to be quilted pretty close to keep everything in place. For a quilt that's only going to be used as a decoration, the quilting can either be much fancier or much farther apart. Once again, each method is "right".
