IKEA hacks is a thing where people take perfectly good IKEA products and then manhandle them for their own, strange ends. In this case, said hack involves taking a normal lightshade and turning it into a frickin' Pokeball. Why anyone would want to do this is beyond me, but I am old, and I do like nice things.
If you fold the crepe paper right and put it all in the right shape, then, voila, giant Pokeball.
I'd probably just end up gluing my fingers together.
