I started by removing the buckle that connects it to a normal shield.
The main portions were of course fashioned from plasticard, the back a thicker version and the front piece was a paper thin section. My wife handled the piece last and shifted the tail-piece without my knowledge. Supposedly accidentally. Women, can't live with them, can't keep them away from your figs.
Here's the rear where I placed the buckle from the standard shield, I bent it to purpose with some rubber bands and placed the buckle inside the curve so it would reinforce and adhere well.
I then drilled some small holes down the middle and placed some miniature beads(found in a household Brita water filters' filter). I battle damaged it quite a bit in hopes of taking the eye away from the misalignment of the thin piece of plasticard. Last of all, I put a large cluster of purity seals to cap it off.
