I put together a quilt with batik accents. No problem sewing it together. I put it on my frame and it's skipping all the stitches JUST on the batik. I've tried every needle from 11 to 14, different weights of thread and I'm stumped. I can't take it apart, I haven't time, it's a wedding gift. Aside from taking it off the frame and quilting it on my regular machine what else should I try? I've used batiks before without problems. As I said, it pieced together fine, so it's not the fabric...or is it? HELP!!!!!!!!!!
