How do I put the drawstring back into my sweatshirt?

I have a beloved sweatshirt whose hood tightens with a shoelace. I just washed and dried it (on delicate), and the shoelace came almost all the way out. Is there a way to get it back in myself, or should I take it to a tailor??

I think this is the most technical question I’ve ever asked on Fluther, haha!
