Editing Component Properties as Editor

We’re redesigning a site using components (for three users), and need a way for editors to make changes without breaking the components. I thought Properties would be the perfect way to allow that, but Editors cannot see the Property functions. Is there another way to lock down the design and styles while allowing Editors to make text and image changes?
