New Rotational Molding Product Design Competition

The following top notch comments from these young, brilliant designers are the comments of the future leaders of the design world.  We are very grateful for the participants and the following comments.  Here are just a few gracious quotes from participants…

“This competition helped me critically think about materials and processes that were initially unknown to me. I learned about the rotomold process while trying to solve a real world problem. This will also is a great piece to add to my portfolio!”

-Sarah Gustafson, Purdue University

Competing in the (Student) Winsell design competition gave me an opportunity to challenge myself. I enjoyed the manufacturing and material constraints, because they pushed me to think more critically about what I wanted to create. In the end, I designed a product that I am happy to show in my portfolio.
Thank you!
Miranda Degg, MIAD Milwaukee Institute of Art and Design
