Hi. Yes the scarf is done with fine tip artist's pens. I also use them for eyes (iris and pupils), eyelashes, and some fine pattern textile detailing. Hmmm...which has just given me an idea .

Not too sure of the brands (they're various), but they are waterproof artist's pens/markers. I think the trick is to wait a day or two for the ink to be well and truly dry, and give several light coats of spray clear coat, and let completely dry between coats. I usually use Testor's Dull Coat, but I'm sure any brand (even Future/Tamiya Flat Coat) will work. Spray - don't brush! BYW...what's a "thobe"?
