Start at the top with on section, start twisting.
Start adding pieces from the sides to match along the same way of the twist.
Okay - for some reason - this is sideways even though I flipped it. But I don't have time to mess around with it right now so next time I'll make sure it's the right way:) Do both sides & when you get to the end of one, I added an elastic & then pinned it so the twist wouldn't let loose. Do the other side the same & bring them together with an elastic of course taking out the pins from holding it previously.
