I've also used Razzle Dazzle and Halo by Superior Threads, these need to go in the bobbin. You stitch with the back of the quilt facing up. If you need to know where to stitch, you can stitch with a water soluble thread from the top side first, then flip it over and stitch from the back side up w/ the thick thread. They work in free motion or with the feed dogs up. When all done stitching, either soak quilt to block or wash after totally finishing with binding and that water soluble thread (Superior Threads) will wash right out.
