Do you know of any white equivalents to graphite that both erase and smudge the same? I know that white colouring pencil and gel pen can be used like what you used here, but they arnt very mistake friendly from my experience and have a bit of a different feel then the darker graphite. The best i could find is soapstone from the welding shop, it works well on gray toned paper like this but does not always show up to bright. I was just wondering if there was anything better.
