For colorful dart origami, use colored paper of different colors to fold triangular components and then insert them together. You can make the dart as big or small as you want, and it looks great!
Prepare a square piece of colored paper and fold it into a "ten" crease.
Fold the four corners to the middle point.
Fold the two adjacent sides.
Turn it over, rotate it 180 degrees, and fold the original top corners upward.
Turn over again.
Fold it in half to get the components.
Insert them together like the picture above.
Until you finish making the colorful darts, if you want to throw them for fun, remember to apply glue to the joints to reinforce them!
