When it comes to yo-yo's the string is actually pretty important. There are lots of different kinds of yo-yo strings. There's mixtures of cotton yo-yo string, mixtures of cotton with polyester, as well as just complete polyester strings. A basic yo-yo string is actually 2 strands of string that have been twisted together. If you ever want to put a yo-yo string on, you would just untwist the string. The 2 stands will separatethen you will open that up and make a loop. Then you open the loop, hold it with your hands, then take the yo-yo and put the loop around one half of the yo-yo gap. Pull the yo-yo to the side, grab the string, and then just let the string twist right back onto the yo-yo.

The next thing you need to learn is how to make a slipknot. A yo-yo string already has a knot at the top but it is not one that will adjust to your finger. So what you need to do is take the loop, put it over the string and then pull the string through the loop. This will make the string adjustable and it will hold on to your finger like so. Now you will want to adjust the string length. Typically you want it from your belly button to the ground. Once you have adjusted the length tie a regular old knot and cut off the excess.
