Starting off we have one of the best introduction videos I have seen by Eric Heart, the Props Master at Triad Stage in North Carolina, who has a book on Prop Making that includes a section on thermoplastics (that you can see here).
This video includes information on working with Worbla’s Finest Art, molding over a form, basic shapes, heating and shaping options, as well as attaching multiple pieces. It also shows the process of creating a bull’s head over a positive mould.
But wait – there’s more!
These videos are some of the first that were created to talk about Worbla, while they’re older they still have a lot of information regarding the basics, so if you’re looking for other starting points, check these out!
