Actually, it's not as hard as I expected... at least, not in the ways I expected.
The marking and scoring of the cardboard is tedious... and I did a shoddy job at it
The cutting and taping are the fun part...
But the folding requires patience, strong wrists, thumbs and shoulders.
You start one side folded in, rotate 90°, fold out, and repeat. But the cardstock gives you a battle every time you turn. What makes it hard is you have to pinch the folds 2 at a time, but you can only make a single corner at a time... hard to explain until you try it.
Lets just say at the end, my shoulder and both thumbs and wrists were pretty sore.
As for the hockey tape, it's much better stuff than I remembered
