Threading the Pigtail Guide on an “M” Big Bobbin Case
‘M’ Bobbin cases will have a pigtail thread guide in the center of the opening. This helps keep the bobbin
thread in line with the needle on larger bobbins, producing a better stitch. You can choose to bypass the
pigtail thread guide on the case if you find it exerts too much pressure for some threads.
Adjusting Bobbin Tension for “L” or “M” Bobbin
Your Beginner Longarm Quilting Class instruction manual includes details about setting your bobbin
tension for different thread combinations in the top and bottom. It is always a good idea to test your
tension on fabric and batting similar to your quilting project so that you can make adjustments before you
begin quilting on a quilt top. Bobbins are available in several different materials, including aluminum,
metal, pre-wound versions and magnetic core.
1.
Hold the thread close to the
bobbin and pull it behind the
pigtail guide, then around
toward the outside of the
pigtail guide in a spiral motion.
2.
Pull the thread tail up,
which will wrap the
thread into the first loop
of the pigtail guide.
Repeat process to wrap
thread through the
second loop of the
pigtail guide.
3.
The thread should pass through
the pigtail guide as you see in the
photo above. When you turn the
bobbin case around so that you
can
see the entire bobbin, verify
that the bobbin is spinning
clockwise before inserting the
bobbin case in the machine.
