My 2nd quilt was Storm at Sea and I didn't know how to quilt the 2 borders, so I put 2 needles and 2 different top threads in my Singer 401a and used a surpentine stitch. It was the first time I tried 2 needles and it worked great. I always forget about all of the stitches on that machine. I think now that I am quilting I will be putting it through its paces more often.
