Cross-cutting cleavage

Okay kiddo, have you seen a paper before? It's made up of lots and lots of tiny fibers that are pressed and glued together. Now, let's imagine you have a big block of paper and you want to cut it into smaller pieces.

Cross-cutting cleavage means that you cut the paper in one direction and then you turn it and cut it again in another direction. Sort of like making a grid on the paper. This is important because it helps make sure that the pieces of paper are even and equal in size.

Now, let's say you were trying to cut the paper without cross-cutting cleavage. You might end up with some pieces that are bigger than others and that would make it harder to use the paper as you want.

So, cross-cutting cleavage is really just a fancy way of making sure that the pieces of paper are all the same size and shape, which is really useful when you're trying to use it for things like drawing or writing or even folding it into cool shapes!
