How Do I Change the Colors at the End of a Row?

To change colors at the end of a row in knitting or crochet, you essentially introduce the new color during the last stitch of the row. Here's how:

1. Work to the Last Stitch: Knit or crochet as usual until you reach the very last stitch of the row.
2. Begin the Last Stitch: Start working the last stitch as you normally would.
3. Stop Before the Final Yarn Over/Pull Through: Stop just before you complete the final yarn over and pull through. You should have loops of the old color on your hook or needle.
4. Drop the Old Color: Leave the old yarn hanging.
5. Pick Up the New Color: Grab your new yarn color.
6. Complete the Stitch with the New Color: Yarn over with the new color (or perform the equivalent yarn over/pull through according to your stitch) and pull through all the loops on your hook/needle, thus finishing the stitch with the new color.
7. Continue with the New Color: Drop the old color and begin working the next row entirely with the new color. You can weave in the ends later to secure them.

This method creates a clean color change at the edge of your work. Remember to weave in your yarn ends securely for a polished finish.
