How long should a Yoyo cord be?
1.The recommended length is from hip to floor but theoretically you can use any length with which you feel comfortable.
How do I attach a string to my finger and yoyo?
2.Always use your middle finger to attach the yoyo (attach it in the middle of your middle finger).
Make a running knot with it, the cord hangs firmly enough on your finger.
3.Never make a knot to connect the yoyo to the string.
All you have to do is untwist the end of the cord and put the yo-yo in and then let the cord twist again to attach the yo-yo with the string.
