Method 1:

First, prepare a square piece of paper. Fold the width of the square paper in half, cut it along the center line and divide it into two halves, then fold the two halves in half with the width. Turn up from the folding line, fold at a 45 angle, and turn up the right half at a 45 angle from the left vertical line. Similarly, fold up the last square to make it look like a periscope. The other half is folded into a folding line with an opening, and the folding direction is opposite to that just now. Then, overlap the planes of the two parts, insert the small corners of the outside into the middle opening, and then align them.

Method 2:

1. Cut off the handles of four plastic knives. Cut off the handles of four picnic plastic knives with scissors or sharp knives. Leave a handle of about 1 inch (2.5 cm) for the blade. This short handle is reserved for folding blades in the future.

2. Glue the two leaves together. Glue the two blades together and overlap the remaining handle. Tie them up with scotch tape. Note that the directions of the two blades should be opposite. One blade faces to the left and the other blade faces to the right.

3. Glue the other two blades together. Glue the other two blades together like the first two. Overlap on the remaining hilt.

4. Connect the two sets of blades together. Overlap the center of one group with the center of another group. Glue the two sets together with transparent glue. Please note that the four blades should face the same direction during operation.

You can trim the edge if you like. Trim the head of each blade to a tip of 1 inch (2.5 cm) with sharp scissors or a knife. This is not necessary, but adding a tip can make darts stick to cardboard and foam targets better.

6. Check your finished product. Play with the flat surface of each blade with your thumb and forefinger. Add adhesive tape as needed to prevent the blade from loosening. At this point, the dart is completed. Only throw darts at inanimate targets such as cardboard and foam, and never throw them at people or animals.
