white ink on black card stock
In the INKed group on FaceBook, people have been sharing about their favourite white ink pen -- the made in Japan Uni-ball Signo UM-153. Fans said, "opaque ink, affordable." Sold. Mine arrived today in an Amazon parcel, along with black art tiles. I sat down at a coffee shop and drew for an hour. The chameleon above was the one I liked best after doodling on about four or five tiles.
