Is it possible to add rows in to a striped scarf after you have passed the section?

[crazytori3]

I am working on a Watson (from the Sherlock Holmes movies) inspired stripped scarf for a friend and recently realized that somehow early on in the scarf I missed one of the light grey rows and went straight on to the brown from the blue. Is there any way to back add those rows? I am almost finished with the scarf and it would be such a bummer to redo all my work.

Any tips on a way to fix this or am I better off leaving it to be quirky?

Thanks!
