Common mistake....
I have a great piece of 80lb cover, yet I'd like to get a paper that is a little bit sturdier (or thicker). I see the 90lb index and am excited that the new paper I'm ordering is going to be thicker and sturdier. As you can see by the chart below, the 90lb index will be slightly thinner and less sturdy compared to my 80lb cover. I am so happy that I made this realization before I have ordered my new paper.
