note : This enables you to move
the material in any direction while
the machine is running.
2. Sew around the areas you desire to
darn. Then move the material back
and forth, sewing out beyond the worn
or open place in the material. Con

26. SEWING ON BUTTONS
1. Remove hinged presser foot and attach button sewing foot. (See Fig. 61)
2. Push drop feed button “DOWN” all the way. (Fig. 65).
3. Set zig zag stitch width at 0. Place the button so that its left hole comes
directly under the needle, then gently lower the presser foot. (Fig. 62)
4. Move zig zag stitch width until the needle comes down exactly over the
right hand hole in the button and lock zig zag position. (Fig. 63) Turn the hand wheel
slowly by hand to be sure the needle enters both holes in button without deflecting
needle, correct width if necessary.
5. When needle goes into the center of each hole, run the machine at medium
speed, making six or eight stitches, stopping with the needle in the left hole.
6. To lock the zig zag stitch and prevent ravelling, set the stitch width at 0, and take
a few stitches in the same hole. If you wish you may place a rounded toothpick
over the button, between the two holes, and sew button to fabric in regular way.
Remove the toothpick and wind thread under the button, forming a shank to
fasten.
Apply the above method to sew on buttons with four holes, hooks and snaps,
etc. If a four hole button is to be sewn, follow the same procedure as for the two
hole button.
Now lift presser foot slightly and move fabric to permit stitching the remaining
two holes, Hooks, snaps, etc., are sewn to the fabric with the same procedure as for
sewing two hole buttons.
