Admissions portfolio for Industrial Design

Hi everyone, I’m new here and love this place already. I am currently getting all my stuff together to apply to a few schools to study ID and it’s safe to say I am pretty clueless. I graduated in 2005 with a Fashion Design degree so not only has it been a while since I’ve been submerged in creativity but I also have no clue what would showcase my potential for ID.

I basically need help on my portfolio. I do have some work I did in school but it’s all pretty updated and would rather show what I am capable of now but have no clue if that could be shown in simple sketches or what. Help! : )

Thanks in advance!
