Stranded knitting is also called Fair Isle knitting where you carry the yarn across the back of your work. Amy has video on it here
The main thing to worry about with stranded knitting is that your loops get too long between stitches. You can trap them in your working yarn if they seem to get too long, but generally if you make sure to stretch your stitches out on the right needle they won't get tight and pucker.
Is there a way to look at the pattern?
The problem with doing it with the bobbins is that all your snowflake stitches go to one end but have no way to go back the other way. That is why intarsia is usually done back and forth. With stranded, the yarn follows you around.
