How do I finish off an item?

I have started to knit a blanket, but, I am not sure how to finish/close it off when I am done. Could someone help me out with this? thanks!!!

You’re going to do something called a bind off. Here is the videos.

You would cast off (a.k.a. bind off). There are a couple of videos on this site that you can learn from.

Also, has videos.

Best of luck and welcome to KH forums!!
