This pattern is Corner to corner, you can customize the size by stopping whenever you like.

IMPORTANT
I have my pattern going from bottom left to top right. I did it that way so that the colour changes would be easier, and you wouldn’t need to carry any unnecessary yarn.

The yarn used was Bernat premium but you can use any worsted weight yarn

IMPORTANT
I recommend watching youtube for tutorials on how to start corner to corner, and how to decrease.
