THE RÜFFLER
The length of the sowing machine stitch also
affects ruffle fullness. Since a given attachment
setting puts an equal amount of fullness into each
stitch regardless of its length, shortening the stitch
(more studies to the inch) makes the ruffle more
full, lengthening the stitdi (few stitches to the inch)
makes it less full For fine, closely spaced gathering
use a short stitdi and an outward adjustment of
the adjusting screw. For deeper, less closely spaced
gathering, turn the adjusting screw inward and use
a medium length stitch.
Material
Insert the material to be gathered between thé
blue blades and through the first separator guide.
Draw to the back of the needle. Lower the presser
bar and stitch. The texture of the fabric influences
the performance of the ruffler as well as the results.
Soft fabrics, cut on the crosswise grain, are best
adapted for gathered ruffles. Always test stitch
length and ruffler setting on a scrap of self fabric
before proceeding with the actual work.
Attaching Ruffle. To form and attach a ruffle in
one operation, place the ruffle strip between the
two blue blades and through the first separator
guide, and the material to which it is to be attached

between the separator blade and the feed of the
machine. Proceed as for plain gathering. Right sides
of the fabric are placed together when the seam
is to fall to the inside.
