I've always made two different styles of blanket. One is low water immersion dyed (LWI) This style isn't as visually striking as the tie dyed rainbow mandalas, but it's very lush. I use a sand wash silk for these blankets which is softer and suits the pastel mottled colours.
Then there is the bright, bold rainbow mandalas. The mandalas are dyed on a 12mm silk habutae.
