Could you show a screenshot please
Actually i was doing it wrong - I just dragged the brush out onto the page and this makes the border appear.
However if I use the brush the 'correct' way - by drawing using the pencil tool then with the line still selected pick a bloody splatter brush - the colour of the brush is it's default black and not what I has selected - in this case green.
How do I change the colour of the brush or do some brushes just support a single colour?
I see the brush forms are black, that's good for a start. Drag the brush to the artboard and check if it's the correct black for the color mode you're in. Then double-click the brush in the brushes palette and check the colorization options: it has to be "Tints". Then you just assign a stroke color which is apllied to the brush
thanks that's me sorted with the tints option set. One other thing - is there anyway to use the eraser tool on this brush? Doesn't seem to be working whenever I try to erase out certain sections of the splatter...
edit: figured it out!
