Near the "search" bar at the top you will see a browse the template gallery button. Clicking this button will take you to category page where you can surf through the hottest templates, or by category including business, cards, holidays, students, and teachers.
The best part is if you have a personal template you want to share, you can upload it here. If you are part of a school domain you can set the permissions of this template to be available for all users within the school, like awards certificates, thanks you cards, or letter head. Students can download resumes, cover letters, and a variety of other starter documents.
Google has so many items to offer, can we keep up with all the snip-its of possibilities?
