Americans for the Arts is the nation's leading nonprofit organization for advancing the arts and arts education. To this end, Americans for the Arts works with cultural and arts service organizations as well as arts educators, arts administrators, artists, and the general public to provide leadership, research, visibility, professional development and advocacy to advance support and resources for the arts in communities across the country. Americans for the Arts continually advances awareness of the arts by pursuing programs and policies consistent with three organizational goals, stated simply: More money for the arts; Arts education for every child; and Community development through the arts.
I like the White Galaxy Marker very much for writing on dark paper, and I have used it to cover another color when I needed to disguise a mistake or simply change effect.
For example, I bought an ornament with name SCARLETT spelled on it and by covering the last 't', I was able to give this to someone with a cat named SCARLET.
If color to be covered is a paint or other pen color, that can make the other color "stain" the white marker tip. This can be avoided if one is sure first color is dry before trying to cover it with white.
I have been using this product for years and find that it works perfectly on my gessoed wood pieces. The biggest complaint I have is that over the years Grumbacher has downsized the size of the bottle, now making it only available in these small, expensive quantities. I would like for them to offer them in a larger size.
