A little trick if you have one is to use a green laser pointer to see what the reflective properties are like of different surfaces.
You would be surprised at what reflects off velvet and some black board paints.Some black board and matt black paints use either a fine grit and or talcum power type materieals .
These tiny particles reflect and fine haze when using a laser.
The velvet gave a very nice pattern of green.
One idea i found on the web and have tried with the laser but not used on the scope yet is a towl (bath towl, towling) dyed black using ordinary flat black paint.
This seals the towl from moisture and acts as a light trap (thousands of tiny baffles)
Of all the surfaces i have bounced the laser off this has shown the most promiss and would like to use optical black paint instead to soak the towl.
