One of my favorite ways to add detail to a coloring page is to layer different media. For example, in this photo I'm adding details with a white gel pen on top of sections that I colored in with marker. I also colored the face of this Matryoshka doll by shading with colored pencils on top of a layer of markers. Markers make a great base layer and you can add colored pencils and gel pens over top to make the art really pop!
This Russian nesting doll is a page in my upcoming Folk Art Coloring Book, which will be available in a few weeks! #matryoshka #russiannestingdoll #coloringbook #coloringpage
