03. Don’t say: “Can you put it in a format that we can edit?”

Why? If you request an editable source file, you’ll likely need specialized design software and risk changing your carefully crafted project for the worse if you don’t have any design knowledge yourself. If you want a professional-quality design but will need to make edits regularly, you might consider a DIY option like Canva, where you can have access to templates created by designers that you can customize or tweak at anytime without compromising design quality.
