For certain embroidery applications, it is desired that the embroidery appear as well on the underside as it does on the top. An example would be embroidery on a sheer chiffon scarf, or embroidery that fuses the top and bottom layers of a quilt together. For this technique, a one-color design works the best. First, fill a bobbin with the same color thread as the top thread, or use bobbin fill that is a color, like black. To accomplish a clean finish on both sides and prevent the underside from having a little pile up of thread, perform the following "Rolling Start" (START, STOP) technique.
Pull the thread through the needle and hold on to it.
We refer to this as the "top thread tail". While holding the top thread tail,
(have it relaxed so as not to cause the needle to bend), press START.
Allow the machine to take only one stitch, then immediately, press STOP.
(Performing this "Rolling Start" procedure may take some practice)
Pull on the top thread tail. The bobbin thread tail will pop to the top
and appear as a loop. Grab the loop and draw the bobbin thread tail completely
to the top. There will then be two thread tails on the top. Press START.
Stitch several stitches to secure the stitching, stop the machine and snip
away both thread tails.
Continue embroidering the design. The underside will have a clean finish.
Make adjustments for color changes and jumps in the design if they exist, or
if a new bobbin is inserted, perform another "Rolling Start" on take off.
