This is what I call a hank of yarn.

Periwinkle, Sky Blue, Aqua, Lime

When I purchase a hank of yarn, I make it into a ball, usually a center pull ball.  Mr. Aitch holds the yarn with outstretched arms and I wind it into a nice center pull ball of yarn.

I don’t do that with yarn already in a center pull ball-type skein like these.  I think they are ready to go.

I call these "center pull" skeins

 I usually pull out the middle hoping to find the end but most of the time it looks like it was disemboweled.

Disemboweled yarn

What’s the secret in finding the end of the yarn in the center of a skein of yarn?  Or do I have it all wrong?

Should I rewind these into my own ball so I can pull the yarn out from the center?

Anyone?
