how to crochet a phone case/ sleeve ( written pattern)

So I have done the video 3 years ago but realised never wrote any pattern for it.

It is an easy and straightforward tutorial and beginner friendly as well, however after this probably within this week I'll be posting an even easier and quicker one for absolute beginners and one you can achieve in half an hour but for now let's write the pattern for this one.

Written Pattern:

Chain the number which fits the width of your phone
