How to make my sketched lines straight

[friendly.lild]

I have a picture that i drew on a piece of paper. Now I am wanting to upload it to Cricut Design Space and turn the image into shirt and sweaters. The issue is i don't know how to make my lines straight in illustrator so that way the shirt looks like it was professionally made and  just nicer all together. can anyone help me with that?

Hard to tell without seeing what you did. How did you turn your sketch into vectors?

Depending on how "sketchy" they are, you may end up putting the scanned art on a locked, non-printing layer and tracing over it with the Pen tool.
