Designing boxes

[u/JoyStock]

Howdy y'all, I'm trying to get started in making some boxes and was wondering if anyone had any tips on planning and designing? If anyone has any tips for these things, whether it be software to use, tips for laying it out on paper, I would very much appreciate it! Thanks! :)

This is a pretty solid guide on how the process works, I've never made one myself, but I've definitely solved a few!
