Homemade String question

How do u keep the springyness of your string when making string?

What do you mean when u say springiness

When twisting and put o n the yoyo, I throw and there is no spring like store bought polys. When I get polys they spring.

Twist it tighter.

Yeah. When you do the chair and drill method, just spin it extra tight.

Yep

Twist it tighter, don’t stretch it.
