How to organize a pencil case?

Here is what I keep in my pencil case:
Pencils, an eraser, a handheld sharpener(optional), scissors, flash drive(only if you use them for your school), red pen, blue/black pen, and a glue stick. I keep my colored pencils/markers in my locker since they take up to much. Feel free to add/subtract any items on the list.
FYI I'm a 6th grader in my first year of middle school. Hope this helped!
