I was today years old when I learned what ‘marle’ is.
Marle
“Also commonly referred to as melange ‘marle’ is a colour effect found in knitted fabrics.”
“The first thing to know is that marle doesn’t affect the texture of a garment - only its visual appearance.”
“It is made by combining two (or more) different coloured yarns in one thread which is then used to construct fabric.“
