So I have I hard time on buying stiffeners. Well, since I have a heard time in my head, understanding rating from 1-10 on stiffness. So did my own little test to help my understand. I have a lot of Luigi Carnevali Microfibra, but never used it. I thought it did not add any stiffness to my projects. But guess it does :)
Anyone else using some of this stuff?
Cool test! Thanks for sharing that.
Nice comparison! I just ordered a few stiffeners to play with, I will do a similar test.
