I've made many costumes as replications of cinematic characters. But this was something different. Cthulhu is a strong part of the popular culture of recent generations, but is seldom seen in three dimensions. There have been a number of visual interpretations of the Great Old One, from video games to South Park. The public does have an image in their mind when they hear "Cthulhu". This character allowed for a costume that could be unique in several ways: it's a costume that no one else would have, or imagine me having, and people may not be able to tell I made myself, because of the complexity of the design and construction method. It would also allow me to be creative and make my own design. All of these unique prospects appealed to me. And I love the challenge of creating extravagant items on a low budget. Producing a full-body latex suit often costs into the thousands. My aim was for under $300.
Prior to my own costume, I had only seen one half-decently made serious costume of Cthulhu. Indeed, there have been many furry costumes and adorable plushies, as Cthulhu has been turned "cutsey". But it's time to get him back to his more monstrous form.
Here is a video you can watch that shows the overall process. It's easier to see some of the steps in motion, but the Instructable has much more information and is more detailed.
