What do you do when you have a roll of about 80m of Purple Satin, and about 30m of Black T shirt material?
You line your Control Room or Obs to keep the dust out and make it darker
I spent today lining the Control Room in Purple Satin and Black material.
There is also sheets of styrofoam behind the material to keep the heat from the sun out
