I want to thank y'all, again, for your patience and help.
I went back to the pattern...ready to try using a cable needle. But after reading the instructions for about the millionth time...I finally realized how to do what it was saying.
And...believe it or not...it did NOT call for a cable needle.
Although the cross over stitch here at KnittingHelp.com says to use a cable needle...my pattern's instructions were as follows:
C2R (Cross 2 Right) = knit into front of 2nd st on left-hand needle, then knit first st, slipping both sts off needle at the same time.
C2L (Cross 2 Left) =knit into back of 2nd st on left-hand needle, then knit first st the usual way, slipping both sts off needle at the same time.
The craziest thing is...now that I've completed nearly the whole back of the sweater (child's)...and I've typed the instructions above...I still don't think I got it quite right (I just realized that on the C2L, I knit in the back of both stitches instead of the first only). However...this is what I ended up with. I think it looks pretty good for my first time ever knitting.

(Even if it's not quite right.)
Here are the stitches up close.
This is what the back of the sweater is shaping up to look like.
Now I'm off to create the sleeve holes.
Wish me luck!
