Can I re-create a pattern?

Hi everyone:muah: I am working on a very simple cardigan… for a toddler, before I make the back 13.5’’’ (it consists of back, front, arms etc.) obviously pieces, can I make this a shrug?.. Just start chopping everything down of few inches:happydance:

you can actually instead just knit it as a rectangle to the appropriate width (the width of the back with the added length of both sleeves) and then seam both of the sleeves. i am not sure how far into it you are yet, so not sure if that will help!
