It's made from white 'cotton casement' - a fabric used for upholstery - some offcut leatherette from a previous holster project, charity shop near-enough belt buckles, brass curtain rings and some washers and buttons sewn atop each other to look like the vents.
The whole thing is scaled up a tad to fit an A4 notebook.
The dirtied /stained / faded colour was achieved before cutting and sewing like this:
soak the white fabric in water, wringing it out, lay it flat.
Use a plant sprayer to spray alternate passes of thinned green and brown acrylics, It will spatter and drip, it wont go on even and it will bleed into the wet fabric unpredictably. PERFECT!
Scrunch it up and force dry it on a radiator.
Total cost £ 11
I also adapted the design to provide extra pockets inside and hidden on the back panel. If yawl want I'll post a diagram.
