I am making my granddaughter a Halloween quilt and saw an add for Superior Nite Lite glow in the dark thread. I thought about getting some and using it on her quilt. Here is a link for it:http://www.superiorthreads.com/shop/...-yds/products/. Has anyone used it before? Is is hard to work with? I would be machine quilting her quilt in the ditch. And what color would you all recommend to use? I used Moda Chic or Treat charm sqares and sashed it in black.
