• ADDITIONAL INFORMATION ABOUT

ROLLED HEMMING

* Hold the thread chain when you begin sewing to

keep it from curling into the seam.

* Place a slight tension on the material in the sewing

direction and a finer seam finish can be obtained.

* The minimum overedge stitch width that can be

obtained for rolled hemming is approximately 1.5

mm (1/16 inch) since the cutting width cannot be

set below 3.5mm (9/64 inch).

• TO SECURE THE ROLLED HEM THREAD

CHAIN

* Apply a small drop of liquid seam sealant to the

end of the seam. Allow to dry, then cut the chain

close to the stitches.

Note: Test the liquid seam sealant for color fastness

before use.
