In the third part of Svetlana Quindt's Tutorial Books Collection you’ll find everything you need to know about building cool props out of EVA foam and Worbla. It covers everything about material explanations, preparation & tools, scaling, creating weapon patterns, separating weapons for transportation, shaping foam, covering foam with Worbla and detail work. She also shows a lot of work examples like Heartseeker Ashe’s bow from League of Legends, a Zweihänder sword from Guild Wars 2 or Malthael’s Scythes from Diablo 3.
This whole tutorial series is quite amazing for cosplay-beginners! Short and straightforward, but you get all needed info nevertheless. Wholehearted recommendation for people interested in the respective topic.
Her method of separating a prop piece into multiple parts for travel and then being able to screw it back together for display blew my mind. It's so simple but I never ever would have thought of it!
