The Plot Thickens

Here's the twist I'm putting into this weaving.

The tartan as seen through sprang worked into the warp while it's still on the loom.

I am working an inset area of sprang in the tartan cloth.  It goes across the entire width of the warp.  This is basic 1/1 interlinked braided structure.

What on earth is this going to be, you ask?
