This is an image of a stencil done in chalk-powder. I got the idea after my experiment with bleach (& I used the same stencil) as another way of creating street art with-out getting in trouble for vandalising. The fact that it's done in chalk means it will eventually wash or fade away. I think the ephemeral quality of these kinds of art works add to the beauty. I made the powder by grinding down the chalk by hand, not sure if u can buy chalk in this form? Let me kno. Maybe u could just use talcum powder.
