Sewing on the heavy fabric
The black button on the left side of the
presser foot will lock the presser foot in a
horizontal position if you push it in before
lowering the presser foot. This ensures even
feeding at the beginning of a seam and
helps when sewing multiple layers of fabric
such as sewing over seams when hemming
jeans.
When you reach the point of an increased
thickness, lower the needle and raise the
presser foot. Press the toe of the foot and
push in the black button, then lower the foot
and continue sewing.
The black button releases automatically
after sewing few stitches.
You also can place another piece of fabric
with the same thickness at the back of the
seam. Or support the presser foot while
feeding by hand and sewing toward the
folded side.
