Two makers break down how to cut a checkerboard jacket so the pattern lines up perfectly across pockets, seams, and diagonals. The welt pockets are the hardest part: getting the checker squares to align requires insane calculations and extensive pinning, but they pulled it off.

Looks like a very basic outerwear jacket or overshirt. Here we have some flat pockets, we have seam allowances, fabrics that must be considered, and the pocket and the flap must be in perfect position to match the whole, and you don't see the one on the back, the color must match. Seems like a very easy garment, but at the end, during the cutting, it's insane. We have to put some pins all over, one by one. This is more or less the same, even more difficult, because here you have a lot of patch pockets with welt zippers and diagonals, and you have to match everything.
This is what she means by welt pocket. The inside here, see the zipper here, inside here, you see the zipper here. That's what a welt pocket is. And the reason it's so complicated in this case is because the welt pocket has to be cut in a way where the checkers align, which is extra complicated.
The calculations were a little bit insane, but we made it.
