I'm doing some SITD work right now to anchor a quilt as I prepare to quilt it. Let me just say that I'm glad I'm SITD with wash-away thread as it is HARD for me to do an accurate SITD. Part of it is I'm working on a new machine. But it is painstaking work to do it right.
SITD may not be the most creative design - but some quilts don't need or scream for elaborate quilting. It is certainly a respectable way to quilt. And if you are happy with it, then that is what matters most.
Cheers, K
