Boy, I am just full of questions huh?

But I am learning
OK, I am working a seed stitch and I noticed that the row I am working from I accidently purled 2 times, and threw off the remainder of my row. What is the best way to fix this? I have half a new row on my right needle that are in pattern, I found my mistake as I was getting ready to knit... so at the moment I have the messed up stitches on my left.
