Quilting (and sewing) with metallic thread can be an exercise in frustration. I have done several projects with metallic threads and have learned a few things that can lessen your frustration levels.
1) Use a metallic or #12 needle.
2) Loosen the upper tension
3) Use a longer stitch length
4) Try running a line of Sewer's Aid (a lubricant) across your spool of thread. Put another drop at the top of your needle.
5) Stitch at a slower rate of speed.
6) Be careful not to put any strain on the needle. Do NOT pull at your fabric as it passes under the needle.
7) You can also try a top-stitching needle if the metallic needle is still not solving the problem for you.
8) Sometimes you may have to use the metallic thread in your bobbin and quilt from the back of the fabric.
If all else fails, try couching the thread. Lay the metallic thread over your desired quilting lines and use a very narrow zig-zag back and forth over hte metallic thread to secure it in place. You can use a clear thread or one that matches your fabric background.
