All those little pieces of batting resulted in this amazing texture and dimension on the finished quilt top:
The silver thread I used above (and below - the little circles around the circle) is Superior's Glitter. It's actually holographic, and is smooth and ribbon-like. It quilts up beautifully, and has a gorgeous sparkle! The only thing I shoudl mention is that if you have the thread coming off over the end of the reel (rather than straight off it sideways) it twists, so don't keep quilting with it too long before you let it untwist. I bought quite a bit of this thread for a planned large wholecloth, and am thrilled with how it looks and sews.
