Foldology Origami Puzzles - Solution for #21

Folding Tips:

1) Pre-crease most of the edges.
2) First, try to put together the big pieces or big folds.
3) Mid-way: choose a piece that's out of position and try to get it where it needs to go.
4) Don't be afraid to unfold and make adjustments.
5) If you get stuck working on the front-side, switch to focusing on the back-side (and vice-versa).

Happy Folding!
