I have built my own using mostly Owens Corning 705 and 703. I prefer to buy commercial products from GIK, because I don't save enough money to make it worthwhile making my own. There is one notable exception. There are back wall areas that I found needed treatment that were shapes and dimensions where commercial products wouldn't fit or would leave too much exposed surface.
It is pretty difficult to make bass traps. Usually, specialized designs and technology is used for those products. However, it isn't hard to make panels to address early reflection points that interfere with imaging.
Sonicjoy is right. Self education is the first step.
