Never thought of doing that on a guitar body…though I’ve seen it on many a lowrider! Great job, when I saw the short I thought it was a fabric or wallpaper top.

Looks great. I think it will be a thin piece of veneer rather than a cap, easy to sand through if not careful lol. Maybe cut a  square of lace. Drawing pin one side to a table top. Then stretch it over body until its tight and pin other side. Will save time and effort taping.  Look forward to seeing end product.
