Yes, I've used them on my DSM with great success. You can use them with decorative stitches, just be sure not to set the stitches wider than the clearances of the throat plate opening. It really does make wonderful embellishments on garments, pillows, and I even did free motion quilting with decorative thread. The needles come in different sizes, as well as the spacing between the needles. The back side of the fabric has a sort of zig-zag, or ladder look because of only a single bobbin thread connecting with the two threads in the needles.
I haven't figured out how to upload pictures to show you any of my work, sorry. :oops:
