Stripes (Changing Color)

So, I want to make a farmer's market/beach bag with a stripe. That looks thick enough (enough rounds).

The easiest way for me to be sure the color change is where I want it is to cut the yarn, work in the end and tie on the new color. I have sometimes just tied the different colors together, but the color change isn't always where I want it when I do it that way.

Fasten on the new color where I want it.

Continue in the pattern.

Finished bag. I sewed on some shells for decoration.
