You have point the reason of why i ask for pattern. I've already make some research and it seems that the "circle" pattern is use for the Batman cape. The Superman cape look like a rectangle but there are too much different pattern i don't know how to adapt it fit for my sizes.No need to feel disappointed, your post has only been up for a day lol. Maybe the fastest solution would be to ask people directly who have already made their Man of Steel suits.
I'm going to be building one myself in the future, but cape patterns are generally pretty simple. You cut a large semi-circle of fabric, with the radius of it being the approximate length you want the cape to be. Cut a much smaller semi-circle in the middle of the flat length of your fabric for a neck hole, and then hem everything to prevent it fraying. Then all you need to do is figure out how you're attaching it, Superman capes tend to be held on with a couple straps that pass under your arms and tie around back before the suit is put on. That's everything I can tell you from my Superman costuming experience lol
Well at least i've a clue now !If I remember correctly someone did post a patten of a cape after getting screwed by the guy he paid to make it for him but I don't know how long ago this happened or who's thread it is.
ThanksThat is some stunning foam work right there. Truly impressive.
