some people use embroidery thread adn it does quilt up nicely. You can get it at www.metroemb.com they have great prices on all of thier threads. I used it when I first started longaming for Practice. Now some customers want it on thier quilts cause it is nice and has a great sheen to it. you can also use www.connectingthreads.com the lots of places online to order. but please do a lil bit of price checking before you make a purchase.
