So, if you don’t want to have to weave in a bunch of ends after changing colors multiple times throughout a project, you can crochet over them as you go.
First, the color change.
Once you’ve turned and are ready to begin the new row, line the tail of the old color and the tail of the new color up along the back of your work, parallel to the rows.
When you put your hook in next, make sure that you go under the two tails so that they will get trapped in the next stitch.
Continue with your row, trapping the tails inside your stitches until the ends of the tails or the end of your row.
After you trim all your sticky-outy ends that you’ve already stitched over;
all you need to do is weave in your very last end.
