I think I use K's method :lol: :lol:
Seriously....I find that I am NOT a perfect quilter and my seams do not always line up perfectly...so I use mono thread for my SITD so that I can keep my stitching straight and it won't show up when I'm not exactly in the ditch on the seam line. I've found that somehow it kinda hides my lack of perfection. :wink:
