That's a great idea! Thanks for sharing!
Last night I did few more tests, including cotton buds sticks(not bad but they are hollow in the centre), and a combination of pva glue and pale saw dust, which I quite like. Didn't think about the bamboo skewers, will try that next.
My fretboard has been already stained black, that helps in terms of contrasts.
Update on the stain & finish.
I am happy the way the DingoTone looks and feels, it smells fantastic as well. It looks matte, which I quite like. I am considering few coats of Tru Oil to add some shine to it, I think that I will do a little test under the pickguard and under the tuners and take it from there.
