To me the texture has always looked like some kind of light diffusion plastic, such as you'd find on a fluorescent light cover, car tail light, or reflector. If not used as-is then they made a negative of it. But since I've never seen anyone using that, what do I know? It's what I'd use though.
I know I've seen food packaging that looked like that as well, though it wouldn't be as durable. Something like the trays that cookies and crackers come in.

have you searched here?
I think there was another thread on these.
(from what I remember that approach was flat plastic pieces molded/curved using by heat)
for a stand.. it was some arcylic pieces cut into webs. like it was suspended or 'catching' it..
maybe try the same approach?
thin, flat plastics/acrylics... (you can textured kinds)
cut to your desired shape(s).. and heat/bend around a sphere (globe, ornament..etc)
adding lights (electronics...etc) is trivial at that point..
unless you want to add some sort of functionality? (blue tooth controlled or other features..etc)
which is still easy.. but not if you have zero electronics exposure..
Well to be fair... an Arduino Pro-Micro costs like $2.00-$3.00 (shipped)
resistors and leds are like pennies...
but I understand.. if you lack the funds,.. you lack the funds.
