Last month I contributed a blog post to BERNINA's We All Sew- utilizing machine embroidery on my B580 with an unexpected material. Mylar! In all honesty, the material I used wasn't even actually mylar but it was cello craft sheets I found online. The transparent color adds a special sparkle to lightly sketch style embroidery. There are also specially digitized embroidery designs for mylar as well. The design I used seen above is available from OESD.
How often do you use machine embroidery in your designs? Is it something you think you'd like to learn or try?
