Help with intarsia, please? It's my first attempt.

Hi, everyone!

I made a chart with photos of the Beatles with the knit pro web application by Microrevolt (http://www.microrevolt.org/knitPro/) and so far so good. My problem is with changing colors. It's a simple black and white project, but I still have problems when switching from one color to the other. What should I do with the yarn when changing? Should I leave it behind? Should I carry it? And how should I carry it, if that's is the case? Or am I doing everything wrong and I should be breaking off the yarn when switching?
The websites I found (http://www.knittinghelp.com/videos/advanced-techniques, http://sweaterscapes.com/intars.htm, just to name a couple) are somewhat helpful, but not enough for me. I need very detailed stuff with lots of pictures and/or videos (yes, I am that hard to teach).
Thanks in advance to anyone wiling to help.

Happy Christmas to all.

In the round, colorwork is easiest in stranding, not intarsia (intarsia is great for flat work, while stranding would probably kill a body if done flat).

Here's a post with a pic of how Eunny Jang handles stranded yarn.  It's best to find a way to get an even tension with stranded knitting.   Some people hold the colors in both hands.  In the round, the colors need to be left inside the work, otherwise you're doing a different technique.

For intarsia, you need to watch the knittinghelp video again.  Amy demonstrates bobbins and how to transition from one color to another--if you don't transition as she recommends, you'll end up with gaps in between colors.  There should be no strands behind in intarsia because your yarn bobbins need to stay in their sections.

Thank you! I'm kind of new at knitting (I mostly crochet) and all I can do is scarves (and badly!), but I thought I would be adventurous enough to do this.
Thanks for the help!

Happy Xmas!
