I put upper tension parts in one, bobbin hook parts in another and so on. When you are putting it back together it helps to know if you have parts left over where they go, or at least a general area that they go. It narrows the search area and can eliminate much of your frustration too. It has helped me countless times over the years.
Best of luck.
