A few weekends ago, I picked up a set of water soluble crayons at an estate sale for $1. They are the Neocolor II crayons from Caran d'Ache. I've been a fan of Caran d'Ache's oil pastels for over 20 years now, so I was curious to see how the aquarelle crayons compared.
When applied dry, the crayons act a lot like wax crayons, except they are denser and richer in color. The magic happens when you add water. Just look at the vibrancy and easy blending of color when a wet brush is applied!
The Neocolor II crayons work beautifully on canvas panel, and I've used them on wood panel, too. Here is a work in progress. I used the water soluble crayons for the yellow moon. I like that I can layer other mediums on top, which is a little trickier to do with oil pastels.
I keep my crayons sorted in a metal slide storage box that I found at the estate sale. I already added some new colors to my collection.
Aquarelle crayons are a wonderful material for kids, too. My daughter used them to make her valentine's card design.
