2. Pierce small holes surrounding the circle use a pencil
 3. Cut the string according to how many holes you pierced.
4. Tie the each of the strings to each of the holes
5.  Attach the small toy to the bottom of the strings if you don't know how to attach the string to the small toy you can use a tape


The parachute is ready
I tested it from the 3rd floor and I succeed
it was really fun making it but I had some problems at  tying the strings because the strings that I used is very small
