Removing section?

I recently started knitting, And as I have gone on, on my scarf, I have realized how bad the first foot of my scarf looks, and I have about 5 ft plus done now. Is there any way to remove the beginning of the scarf, and then just continue knitting to make up for that lost foot? if so, how? Thanks!

You can undo the cast on and unravel it, or cut a stitch above what you want to take off, put the sts on a needle and reknit that section or just bind off.
