Love the decorations on the cloaks. Is there a secrete you wish to share with us?
They're just dark triangles of colour (on the robes), usually contrasting with the robe, with a bright-ish highlight of the base colour added. I think the secret is to be very careful about the shape and placement of the dark triangles of colour and to keep them consistent around the fabric to give the sense of a pattern. I hope that makes sense?
What manufacturer are they.
They're Artizan Designs Erik, I've had them for well over a decade and they really needed to see some paint!
