This is probably a really simple question but I haven’t been knitting long so please don’t laugh 
My pattern says s1, k2tog. All the sites I’v been looking at so far talk about s1 in combination with another stich but never with K2tog.
Now my question is: shoudl I use s1 on its own? And how is it done?
If not, then I guess it should be used with k2tog (as in my pattern) bbut I am not sure how to do this either. (I know k2tog though).
Any help will be much appreciated.
Thanks
