Yummy Gummy Latex

I was looking for a source of small quantities of coloured latex yesterday when I stumbled across https://yummygummylatex.com/ who hand make all sorts of 'out-of-the-ordinary' sheet rubber.

   

I'm particularly intrigued by the colours they chose for their their example of double-sided latex. I spent ages glueing purple and yellow sheets together to make my Batgirl cape and now I wonder whether I wasn't beaten to it...
