The velvet?  Pretty simple, actually.  I used the following pigment within a
sky_sphere.

// A red velvet-like texture
// Michael D Johnson (red### [at] wvadelphianet)
// Use freely.  But give me credit if you can :-)
#declare C_Reds = color_map { [0.0 Black][1.0 Red * 0.5] }

pigment
{
 average
 pigment_map
 {
  [1.00
   bozo
   color_map { C_Reds}
   sine_wave frequency 4 scale 0.25
   turbulence 0.5
   omega 0.5 octaves 3 lambda 2
  ]
  [0.90
   bozo
   color_map { C_Reds}
   scallop_wave frequency 2 scale 0.25
   turbulence 0.9
   omega 0.75 octaves 4 lambda 2.5
   rotate y * 45
  ]
 }
}

Enjoy!
Michael
