Q.L. Tutorial to make an A.B. Mask designed by a nurse (Part Two)

I've been working to make lots of these A.B masks designed by a nurse for family and close friends.  This set was for my neighbors who are huge fans of Star Wars and Harry Potter.

In the second part of the tutorial, I will show the use of continuous bias binding for the edges and the ties.  I've shared this magical source before called the Quilters Strip Ticket. (I'm not putting a link in because I don't want to favor one source over another.  It seems that just about every website that sells sewing notions carries them.) If you are a quilter and don't own one, it will be the best less-than-five-dollars you've ever spent.  One side provides detailed drawings of the construction and the other side is filled with charts telling you what size square you need to cut the width of tape you want.  In the case of the masks, a 13 1/2-inch square provides the exact amount of  one and a half inch tape you will need for one mask.

 Whether you use the Quilters Strip Ticket or the method
in the nurse's directions, the ends of the continuous bias will
end in a 45 degree angle.  I use these ends to bind the sides of
the mask. Pin in the bias to the WRONG side of the mask.  Once you've done this, you can trim off the excess.  Using a quarter-inch seam, sew it in place.

 Press the binding up and then press under one quarter inch.

Fold the binding down over the pleats on the RIGHT side of the mask and sew close to the edge.  Trim binding even with
 the edges of the mask. Repeat for the other side of the mask.
This gives a nice finished look to the front of the mask and, yes, I know it's two steps, but this way you don't have to
 worry about trying to catch both sides of the binding if you
try to sew it in two steps.

 Cut the remaining bias strip in half and press one side under one quarter inch.

Finally, fold each of the strips in half and press to mark the
center. When you attach the strips, you want to center them
in the middle of the mask so your ties are even.

In Part Three, the top and bottom of the mask will get bound
and the ties created.
