The 5 cardboard techniques that I used were scoring, slotting, tabs, notching, and the butt joint. 

These are 5 small projects i made, each of them a different cardboard construction method, so that I could improve my skills with cardboard. I have layering, brads, a butt joint, scoring, and folding.

Scoring, Brad, Tabs, Slot + Tab, Slotting

I didn't learn much from this practice because we have already done a class on cardboard connections.

I do this a lot so no new insights came to me. The strongest connection is the triangle. Can and should be used for anything.
