This is definitely an interesting question and it'd require more study in Origami world. Being able to relate spatially would definitely help when it comes to designing and folding. If you've got good spatial relation skills, it will be easy to tell where a certain crease or area of the kraft paper will end up whenever a fold is made. I bet following complex diagram can also help out for the same reason.

Interestingly for me, I've got quite a low processing speed meaning it takes me hours to decode a large amount of information, yet I consider myself a fairly fast folder. So, I'll probably say that my spatial relation skills override my low processing speed.

I got mine from Terry's store. It comes out thinner than the mostly used kraft papers and it holds creases firmly. It is perfect for the ryujin but may be too thin for the black forest cuckoo clock.
