I ordered variegated cotton quilting threads (King Tut) from Superior Thread. I also recommend the Bottom Line for your bobbin thread, you don't have to wind bobbins so often with this product.Shipping is only 3.95 per order. Might be a little pricey,treat yourself to one or two spools to see if you like them. You get quality quilting and sewing threads and great service. Check them out at superiorthreads.com.
