Slash them all again in the same spot,then add the black, and again add a different fabric to the other side. Slash again... Wash, rinse, repeat. Does that make any sense? At least that is my best guess from looking at it. I bet it would be fun. I might try it for my toddler for Christmas anyhow.
Makes total sense ... and probable more so than if I'd tried to explain it!
It's a Slash-The-Stash technique.
The easiest way to get them to be all slashed in the same place .... stack them up into one pile. Or if too many fabrics, then two piles, etc.
At the end you will need to square them all up, as they may have gotten slightly off-sized or off-square with all the slashing, piecing and stitching.
