dog sweater with snowflakes

[Jade731]

I want to try to knit a sweater with snowflakes for my dog. The pattern is not solid all the way across the line, so I wanted to know how I would be able to switch yarn colors and make sure that it doesn't come loose.

I know that if you switch yarns in a row or add a new ball of yarn you knit both yarns together but will the old color show if I'm trying to knit a pattern?

I"m a beginner knitter, so I just want something simple.

Does this look easy to do. http://doublepointed.files.wordpress...og-sweater.pdf
