How I make bows

Take a piece of fabric that is wider than it is long, and fold it in
half with right sides together.  

Sew down the sides and across the top.
Leave a small gap in the center to turn the fabric
right side out.
Turn right side out and iron flat. (You may want to either
top stitch over the entire thing, or just do a quick whip
stitch to close the hole in the center where you turned
the fabric right side out)

Fold in half.

Fold half up from center
Flip and fold other half up
Pinch in the center

Stitch all the way through the bow until you
come out with a shape you like
