In order to neatly fold the top of section B over the shears, and also
to make the shears case more interesting, cut the flap as shown above.
Measure ½ inch from the sides of fabric piece B—points a and b. Then
measure 2 inches from the top of section B—points c and d.
Using a ruler, draw a straight line between points a and c and points b
and d. Cut along a-c and b-d with long, even strokes.
