Before soaking the Saturn cape in water I thought I'd do a dry run trying out the best way to fold it.
I immediately remembered how stiff this cape is, being two layers of material fused back to back.
It gave me no hope that water would work. I imagined the folds popping right back out when dry.
The next option was a steam iron. I haven't used an iron in maybe twenty years, because I never wear anything that needs ironing!
Well, that was until a few days ago when I found a forgotten pair of jeans in a drawer that needed shortening. I found turn up tape and dug out the iron.
Steam ironing turned out to be strangely therapeutic activity.
I folded each side over his shoulder in one large triangle, then folded it forwards over itself.
I gathered the excess material at the back and ironed it so that it holds a lighter fold:
It's not an ideal solution because the material isn't draping naturally, but being forced to conform to a set design.
However, it's no longer an unwieldy stiff board so I'll take this alternative.
