Leaving the leaf in the center of the paper, grab the outer edges of the paper, opposite you, and pull those edges towards you to meet the edges closest to you. This should look like it's folded perfectly in half, longways.
With the long edges aligned, fold them back about a half an inch, and then back again another half an inch. Continue this process until you reach the pastel, and then roll that folded edge until it lies right along the middle of the pastel.
Now that the pastel is completely folded longways, it's time to fold in the sides. Using the side of your palm, smooth the paper, pushing the pastel from each side towards the middle. Then, tuck one end of the paper into the other, like an envelope.
Cut a long piece of butcher's twine, about 30", and lay it flat on the table in front of you in a straight line.
Lay the wrapped pastel right on top of the middle of the string. The string should sit crosswise under the center—like a belt waiting to be buckled.
Bring both ends of the string up and over the pastel. Tie one simple knot, think of the first step of tying a shoelace. Don't tighten too hard yet; just anchor the bundle.
Take the loose ends of the string and pull them along the long edges of the pastel. Flip the pastel over gently.Tie another simple knot on the opposite side.Now the pastel has its first "belt" Without cutting the string, bring both ends around the shorter sides of the pastel.Cross the strings so they make a clear X. This is the iconic "cruzado" shape, also known as the Double-Cross Tie.Flip the pastel again and tie another knot to secure this second direction. Tie one more firm knot on top.You want it tight enough to hold during boiling, but not so tight that it tears the paper. Your pastel should now look like a neat, rectangular package with: ° A secure knot on each side° Two looping “belts”° A crisp X shape across the topIt’s ready for the boiling pot!
