Hello, my name is Brittany!
I just learned how to knit last night. I have a huge problem though and no one to help me!
i was at the end of a row and 4 stitches slid off the needle. i slid them back on but now the string (or where the end would normally be) is behind the three stitches. I hope I didn't ruin it!

Put those dropped stitches back on your left needle and just knit them again. It is an easy fix.

if you're a right handed knitter:

slide the stitches to the right of the string on the right handed needle, the stitches to the left on the left handed needle. then just continue working your stitches.
