The Birdcage Veil
Birdcage veils are made out of Russian Netting or Russian Veiling which is a millinery material. You can usually find it at a really good fabric store or online.
The veiling usually comes in three lengths 9" 12" and 18".
If you want it to cover your eyes, you'll want 12" and if you want it to cover your nose or chin you'll want the 18" veiling (cut it down to 16" to cover the nose.)
It comes in almost every color and you can also find veiling with chenille dots or pearls if you wanted to add embellishment in that way
