What are good options in colored pencil blending, especially for a traveller? I generally use the Faber-Castell Colored Pencils, which are vegetable oil based, but I also use PrismaColor Premier from time to time. I normally use Odorless Mineral Spirits to blend, but it is a toxic substance and so not something I normally want to travel with. What are some other possibilities for blending that can be used, especially for those that want to work on their art when traveling?
PrismaColor has a colorless blender pencil.
Further, you could layer colours (start with the darkest) and use a (near) white pencil to burnish the colours. Make sure the tip of your pencil is sharp and apply the colour in small circular motions to get an even result.
