No extreme difficult folds have to be made to create this complex looking dahlia flower.
Step 1:Both sides of this paper are purple.
Prefold over these 4 lines.
Step 2:
Make a valley-fold over these 4 lines.
Step 3:
Make a valley-fold over these 4 lines.
Step 4:
Prefold over these 4 lines.
Step 5:
Start with making a valley-fold over the 2 lines indicated
by the arrows. Then, make a mountain-fold over the 2 lines
next to the first ones. Continue making valley- and
mountain-folds until the 2 lines on the top-left.
Step 6:
Prefold over these 4 lines.
Step 7:
Unfold the model until it has the same shape as in
step 5 again.
Step 8:
Fold the piece in the center downwards by making
mountain-folds over these lines.
These lines are prefolded in step 6 (the yellow line below
in the picture of step 6)
Step 9:
Fold the piece in the center upwards now by making
valley-folds over these prefolded lines.
Step 10:
Fold the piece in the center downwards again by making
mountain-folds over these prefolded lines.
Step 11:
And fold the center piece upwards one more time by
making valley-folds over these prefolded lines
(The upper line in the picture of step 6)
Step 12:
Now the model looks like this.
Step 13:
Fold the petal upwards by making an inside reverse fold
over these 3 lines.
Step 14:
Fold the same petal downwards by making an inside reverse
fold over these 3 lines.
Step 15:
And fold the petal upwards again by making an inside
reverse fold over these 3 lines.
Step 16:
Repeat steps 13 to 15 on the other 7 petals.
Step 17:
Now the model looks like this from above.
Step 18:
Fold the corner indicated by the arrow downwards by
making an inside reverse fold over the 3 yellow lines.
Make a mountain-fold over the short line in the middle
and a valley-fold over the 2 longer outer lines.
