WOW, what great ideas for sewing with the metalic threads. Let me toss in one more. Instead of a regular 90/14 needle, buy the "metallic" needle in 90/14. The needle is much larger, the groove above the needle is deep to help guide the thread into the needle correctly. Add that to the other fantastic suggestion and you'll be home free.
Your quilt is wonderful. I love the use of the metalic thread around the paisley. It is just beautiful and will be such a treasure when finished. Good for you for doing something so wonderful for yourself.
