Knitting stripes

[snakeling]

I want to start a scarf, that I would knit in 1x1 ribbing. I mean to do stripes in two colours, 6 rows of one (red), 2 of the other (yellow).

I'm going to weave the red yarn on the side of the yellow stripes, but I'm unsure what to do about the yellow yarn. I started weaving it on the side, but it definitely shows. Is there a trick to hide it, or should I cut the ends every time?
