Brusho test - Doreen O'Clairy

So I got this stuff called Brusho after getting introduced to it by Becca Hilburn (seriously, her youtube channel is awesome and full of helpful art tutorials!)

Apparently this stuff is used in the UK or something in schools?  I can see why.  It goes well with a recent technique I've been using of filling an area with water, and then letting the color spread... Then I go in and darken it as I need.

ANYWAY.  This stuff is cool, but I need to do lightfastness tests, oh my.

Doreen belongs to Magical-Mama, blah blah blah okay guys
