I've seen on the web people mentioning that they use copic or prisma colour markers for shading. I'm under the impression that if you don't airbrush, you can actually draw the shading on to your needle felting? Does anyone actually do this? Do you need to somehow blend the ink? Does the finished product look like you've taken a marker to your work?
Any info would be very much appreciated.
Narelle, we have a library (located on the left just above your post) that has a whole section devoted to this issue. Go there and click on "Airbrushing/Painting/Shading". I use Prismacolor permanent markers to shade and use a blender marker to - well - blend the colors.
