You can make a chevron using 1/2 square triangles, too. It is really easy. What I do is cut a strip of the main fabric(s) in whatever size you choose to make the chevrons. Then cut an equally sized strip of the white.
Put the two strips good side to good side, and sew 1/4 inch seams the length of the strip on both sides. You wind up with a tube.
Cut the sdwn together strips at intervals that are equal to the length of the tube. So if your strips are 5" long and forty inches wide (excluding selvage) you will get 8 squares. If your tube is 10 long and 40 inches wide, you will get 4 10" squares out of the tube.
Take each square and sew the open ends together. Now each of your squares is sewn closed on 4 sides.
Take your ruler and put it on the square and very carefully cut it on the diagonals, corner to corner, like you are making an "X".
You have 4 quarter square triangles and did not sew on the bias. Arrange them for the chevron. Here are two that I have done. I only use two fabrics for the chevron, but you could use more than that, if you want. This technique can also be used for hourglass and pinwheel blocks, etc.
