It's not just savi g your projects. You should choose some of your best work that show different qualities and compile them into a single pdf file. You can include anything from your school projects to your own personal achievements in there. Make sure to add your name and other relevant information in order for people to contact you easily. Also, when you compile your works don't just put everything on the pages randomly. Try to categorize your projects. Make sure you put the personal ones last if you want It to be more professional. My final advice would be to GOOGLE. I shouldn't have to tell you that Google is a great source of knowledge for creativity. So look it up on "Pinterest" You can also ask your seniors for their portfolio to see what it's about. I'm sure they'll be happy to help you. ....all the best to you...cheers
