Common parts and a unique crease pattern
Now that we have done a full crease pattern from start to finish, it's time to learn some more patterns often found in models with pleats, and incorporate our new knowledge into a unique model. Recall pleats are alternating mountain and valley folds folded parallel to each other, and pleats are used often for very narrow appendages and fingers/toes.
Piece 1 (claws or toes)
Here is our first pattern:

Remember,
1) Start with the long creases, and later on do the smaller creases.
2) Start with the creases nearest the edge of the paper as valley folds for white side up, and
3) Alternate crease directions around nodes.
If you want the solution, click here.
You will notice that if you choose to collapse the model by starting with only the long creases, that the shorter creases are formed by reverse folding back and forth to form 3 points. This illistrates what exactly a reverse fold does. The solution to the crease pattern has lines A and B reversing direction whenever the lines meet a node. This direction reversal is a reverse fold. In many crease patterns you will see a direction reversal in a crease, and you know that a reverse fold has formed it.
Here is the completed pattern (color side up):

Piece 2 (long appendage)
Here is our second crease pattern:

This one may look complicated, but if you follow the 3 rules you will not find it too hard. I will show how to apply the rules now. For rule 1, we should do first the longer creases. Let's do simply this cp instead as an intermediary to the finished model:

We start with valley folds nearest the edges for our model, and alternate crease directions. Here is the model collapse in progress (color side up):

You notice that the long diagonal crease alternates direction, this is because if you do this pattern step by step, you would be reverse folding over and over again.
Now, to fill in the smaller creases as details, you could A) crease each small crease before collapsing, and do it all at once, or B) Do it as I have learned to for this particular pattern, squash each corner. The squashing is shown here (color side up):

And here (white side up):

The solution to the crease pattern is here.
Putting the pieces together
Now, Let's put all our parts together and make something interesting. We will make the following morphed bird:

Here is the crease pattern for our bird:

You have already done each of the 3 pieces of the model, so filling in the directions of the creases should be a matter of copying. I am providing the solution here.
You see that all of our rules learned so far are still being followed. This is promising for future models that will require more and more folds and complexity.
