There are Christine Hiebert's blue tape drawings, lovely masking tape lines on large walls, and there are her charcoal drawings. Her website shows drawings that are transparent and layered: the clarity and high-contrast of tape on painted drywall translated to charcoal mark-making. One of the addictive tendencies of charcoal is its smudging – a clear mark made by a stick is then made ambiguous by the hand, but Hiebert uses an array of charcoal, ink and pencil lines precisely as they hit the page, each of which outline a space on the page that intersects and overlaps other line-drawn spaces.
The wide bands, the width of a char-kole stick, or a graphite stick (each giving a different density of particles on paper) reveal both their own qualities plus the qualities of the paper. They are laid down by a hand on an arm that follows its own rules.
