How do you use a blind stitch on a sewing machine? (Fig 6)
1 Press the raw edge by about 1½ inch or zigzag it if you’re using a heavy fabric
2 Press the edge again by the seam allowance and pin
3 Fold the hem backward, so you’ll be left with around 1/8 inch of material poking out the edge

4 Select the blind stitch setting on the sewing machine with the stitch set to 2 in width and length
5 Remove the current foot and put in the blind hem foot on the sewing machine
6 Place the fabric under the machine and align the foot guide with the folded edge
7 Begin sewing as usual and then fold the hem down to pull the stitches vertically
