Assemble several plastic sheets (choose any colours of your liking) and stack them one on top of the other to create a pile.
Imagine a strip at the centre. You may even fold the sheets to find the natural point. The strip will act as a handle, therefore, adjust the width of the strip according to your convenience.
Cut the fringes from either end. You may alter the width of these fringes. Be careful of the strip, making sure that the cuts do not invade it.
Gather the plastic stacks at the strip. Tie a piece of fishing wire or tape on it.
Fluff out the strips, making sure that no two pieces stick to each other.
