I can't even imagine how that is done! Do you have a link to the video>
Looked around and finally found it online http://www.youtube.com/watch?v=Gz...
Several years ago I decorated a purse with bobbin work and I am still using it and getting compliments. The hardest part is hand winding the bobbins but it doesn't take long. I used a variety of threads and narrow braids and used several of the decorative stitches that look entirely different upside down. You do have to adjust the tension and if you are uneasy messing with the screw on your bobbin case, most machines have bobbin cases designed for bobbin work. I got the Viking one and do not regret the expense.
PS - You can free hand or sketch a design on the stabilizer. I rambled on the purse but have also worked more formal designs. This isn't a technique you would do every day. I have never tried it on the embroidery unit but I don't see why you can't if you slow the speed. (I am not an expert; just adventurous.)
whenever i want to use gold or silver threads i put it into the bobbin and do what you are calling bobbin work.,This is great for those special cards and no need to mess with the bobbin screw. i also use the slightly thicker threads that have a problem going through the needle. Try doing red work using this method on the reverse of the fabric.
I have a special bobbin case for my Husqvarna Designer. Only used it for sewing fancy stitches, not for embroidery. The results are nice, I don't get extra fluff but clean the bobbin case whenever I change bobbins, sewing or embroidering.
I have done a little bobbin work. You have to wind the thread, yarn, etc. on the bobbin by hand and play with the tension. You also want to make sure that the wrong side of the item faces up when you stitch. It takes a little playing with, but it can really look great when you're finished.
That sounds interesting - I'd never heard of it before.
I have the Ellisimo and there are special designs just for bobbin work and a an additional bobbin case...It is really beautiful and you can use all sorts of different threads and ribbons, etc...I have also done some free motion bobbin work just on my regular sewing machine...
