Yarn question

Hi everyone,
I usually crochet and finally got my nerve up and I am slowly
trying to learn to knit. I usually use cheap yarn and just
discovered yarn store with wonderful yarns. I bought a skein
of Cascade Fixation and for the life of me, I do not know how
to find the yarn end that you pull out of the middle since it is very
tightly packed. Any ideas before I pull out the whole middle?
Thanks!

Stick in a finger from both ends and wiggle them around. You should be able to latch hold of something.
