I am relatively new to knitting and I am knitting this striped scarf. I am knitting in straight garter stitch and changing colors from white to blue. To change colors I am dropping the old color and adding the new at the beginning of a row. At the end of my first row of color change though, I seem to have the previous color present in the new color. :( What am I doing wrong here and how can I fix it?
One thing I think would help prevent this would be: when you get to the end of the row prior to changing your color, go ahead and knit your last stitch on that row using your new color, turn, and continue knitting with that same new color. (Don't really know if that makes sense or not.)
