Body: <p>I am on step 81 and just realized that the small parts have a wavy and straight side and that I have to put them a certain way, I’m not sure if all of them are the correct order will this affect my build? If it shows that the wavy side is on the inside and I put it on the outside?</p>

  "Wavy" feature isn't really used that much these days. But the reason one of the ends is wavy is illustrated in answer by username_2 De username_2.
