Help with splitting a wide scarf

Hi,

I have knitted a scarf for the first time and have overdone it on the width (I reckon I can probably halve it!).

Is there anyway that I can do this without unpicking all my hard work and starting again?

If anyone can help me, I’d be so grateful!

Thanks to all

Well first of all, congrats on finishing your first scarf. Depending on the weight of yarn and the thickness of the stitch pattern, you might fold each end in toward the middle and seam the long edge and both ends. That’ll work especially if the yarn isn’t to thick and it’ll be very warm and cozy.
