Homemade Reflection Filter or Microphone Isolation Panel

I have had my problems with recording vocals.  One of them is simply my vocal ability.  However, I figure that if I limit the other issues, I can focus on improving the ability more easily.  A reflection filter eliminates the ambient noise in a room, allowing you to control what sound gets into the microphone.  It isn't as good as an isolation booth in a real studio, but it works.

I made a reflection filter instead of spending the $100 to $300 for one.  I have certainly been pleased with the results and also the price tag ($15).  If you have had similar issues with home recording, this should be helpful to you as well.
