gaping46and2They are probably a bit fine for hand embroidery. We're planning to eventually sell the 12wt which would be better for hand embroidery.
Aurifil does advertise that these work well for machine embroidery. Can't say that I've tried it myself but here's a link to the information on the Aurifil site if you want to check it out.
