I've been working on Briar from league of legends and her prop is HUGE! it's all made of EVA foam + a small bit of Sintra for the outer spike support. It's insanely lightweight I'm not sure if it weighs more than 12kgs honestly and it's really easy to move around in! A lot of people have been curious about how I will wear this so I wanted to demonstrate how it works!
And of course I created a pattern for this so it will be available soon
