a length of twine at least as long as the drawstring (I used hemp string as that's what I had, but any type will do)
a medium length zip tie
your hoodie drawstring
Tie the twine to the loop (like a needle and thread).
**as a side note the reason I didn't just attach the zip tie to the drawstring is I didn't want to make the drawstring holes any bigger by pushing large knots through and the twine is a bit easier to move through the hood.
Continue to feed the "needle" through scrunching the hoodie up on to the needle then straightening it out to advance the "needle" until you get to the other side.
Feed the tip of the drawstring through the first hole.
Untie the twine (or cut it carefully) and you are done. Congratulations your hoodie is restored :)
**May I suggest tying a knot or double knot in the end of the drawstring to help prevent a relapse. Or invest in some cheap toggles.
