This would work well for large wings that need to be especially durable, and best if they'd be seen from further away. I would be really interested in making plush wings for babies. No wire or pokey bits, safe for teething and such. Materials Main material Hose, like thigh highs or panty hose are what I usually use. They're very durable and pretty, somewhat see-through, and take paint well.
Netting is a similar option, cheaper, a little coarser.
Also, in the way it has to be attached, it's not quite as sturdy. Maybe a little more durable than Netting, especially because it would be easier to sew on. Secondary materials Paint - puffy paint, paint that soaks into the fabric shiny vs. matte finish plain colors vs. sparkly, shimmery, etc. Send it to me. One thing to keep in mind - the simpler shapes, bug shapes, butterfly, very rounded work for hose.
