Figheadair, thanks so much for helping clarify!!!! I have tried many, many searches over the past weeks to try to find an image like this. SO helpful.

I have some extra (gads acrylic plaid fabric) tartan that I can make several attempts to get the construction figured out. (The acrylic fabric was inexpensive, and the only available in the tartan I wanted, unable to get any response from many enquiries to tartan designer/seller so please don't judge me. )

Once I have a chance to get into this project, I will post pictures, and probably ask a whole lot more questions!
