I currently have a melamine rack and am expanding my collection, only thing is I want my next rack to be lighter. When I go in home depot and ask about pvc sheets they look at me like i have 5 heads and try to sell me pipes what should I ask them for if it is available there. What are some websites I could use to find it as well. Cost of material isn't too important as it will most definitely come out cheaper homemade than custom ordered. I plan on making a picture tutorial on how to make one as soon as I begin building
