Unravelling a row.....?

How-to Questions
1

So I changed colours one row too early. I am about half way through the row and want to unravel it but I have never done that before. I am ALMOST finished this project and I dont wanna screw it up. How do I unravel and go back???

For half a row, just unknit the stitches. Put your left needle into the st below the one on the right needle, pull out the right needle and pull the yarn. Repeat.
