Going back to building materials for practice:
I suggest having someone who isn't afraid to make it hard build it for you, instead of building it yourself. If you build it yourself, then no matter how much you deny it you're going to remember how you attached different things. My partner and I always ask our coach to make something, because she enjoys watching us trying to recreate her insanely difficult structures. It's kind of evil, actually.
Also, I just realized that all those times I wrote out the names of the different K'Next pieces, I could've just made a key at the beginning.

Wow, no wonder it takes me so long to write instructions.
