angelwings

Many times when I see feathers, so beautiful.....I wonder how would a wing of an angel look like...????
Is is made of the kind of velvet soft butterflywing material, or more like feathers of a bird, or more transparent like the wings of a dragonfly?
Somehow its none of them, but way more beautiful in ways I cannot imagine, would love to see it....or even touch it... get a glance of an idea...of that beauty.
