Be careful if you try to do it by machine..I did that, and the "automatic threader" thingy got hung up in it and pulled out.....the little piece looked kinda like a staple..only smaller......to replace it (Bernina) cost about $40.00, so I would have been better off just tossing the pieces. Now I do it by hand, with large and loose stitches..just to hold it together until it gets stitched down with the quilting.
