Dry brushing fleece?

Sorry for the frequent questions. ;^;
Been working on my head, and so far the dry brushing has gone great for shading. But now I need lots of spots. Some of them will be quite tiny, but they still need to be defined.

Straight-up paint causes the spots to be hard and crusty. :c Are there any alternatives to acrylic paint that won't bleed or make it look crusty? Would alcohol-based markers (like copics) work? Fabric paint? a dye or ink?
