This week's Diva Challenge is to use a black tile or anything found black. I have some of the black Zentangle tiles but don't use them often. I find that I cannot get the white pens to be as detailed as I would like. They don't flow like the Sakura micron pens. In fact the one that worked the best for me was the Signo uniball pen. I did love, love, love the Zentangle soapstone stick for shading. I could shade all day on black with it! They seem like a hard rock but lay down a soft white misty shade of white on the black paper. It was fun but I doubt I'll be a lover of the black tiles anytime soon.
