You might be asking why Copic markers and rocks, well let me explain. In case you have not heard rock painting is a thing. There are groups of people all over the place that paint and hide rocks for other people to find. They are meant to be inspirational and brighten someones day. I'm part of a local group.
Here are some rocks from my last batch that I painted. These were done with acrylic paints and black markers.
I've even water colored some. But what I have never tried was Copic markers on a rock. I saw in a group some where on Facebook that someone had used the Chameleon markers so I figured why not try Copics.
I started with my rock and a inked line drawing on my rock. A simple fairy door. The thicker lines were done using Staedtler
Lumocolor and the thin lines in the door and window using a fountain
I went on to color in the window using Y15 and YR12, again avoiding the Lumocolor lines.
Next I colored in the stone around the door and at the bottom of the door using W2, W3 and W5.
Do Copics work on rock? Yes they absolutely do. However I will use a liner pen that is Copic friendly next time. I just did not think to test out the Lumocolor first so that was my fault for using it.
