You will need 1 3/4- 2 yards of fabric (this will make 2 scarves but you need this much to get the necessary length… do 1 3/4 if you want your scarf to be a little closer around the neck, 2 if you want it longer & looser). Wash and dry it. Then cut your fabric in half, cutting it so that you have two pieces that measure 1 3/4 or 2 yards long by half of the width of your fabric. Each one of these rectangles will make a scarf. I ended up with two rectangles that measured 22 inches X 66 inches or so.
Set one of your pieces aside. Take the other piece and square it off. Basically this just means that you make sure that all the sides are cut evenly and straight and that the corner angles are 45 degrees. To do this I folded my piece of fabric in half width-wise and used my quilting ruler, rotary cutter, and self-healing mat. Then unfold it.
