Dust weaving

I have multiple questions about dust

1.Can it be weaved into clothing?
2.Can it be weaved into hair?
3.Can it be be made into a tattoo?
4.If any of the above is correct, does it give you the ability to use the element without a weapon?

1. Yes, this practice was declared common in the show. Volume 2- Chapter 8: Field Trip for reference
2. This is trickier, but I'd say yes if the hair is braided/processed (ie Android or Synthetic hair to explain "processed")
3. Given the volatile and explosive nature of dust, no
4. Yes

Weaving dust into clothing here however is not "Oh I did it once, I now have a coat that can spew limitless fire." You would need to buy the dust and weave X number of fire dust posts into it. After that many posts are used the fire abilities would then be lost from the coat until more dust was weaved into it.
