OK so I went out and bought 2 kinds of tulle and a headband today.
Found a diagram online and set to work.
I sewed almost completely along the cut edges of the tulle and pulled it so the fabric gathered. It really shapes the veil nicely when you gather it.
Then I sewed it to the headband. Here are some pics of my 1st try. I'm pretty pleased actually....I have never been especially good at sewing lol

its longer than the veil I tried on last week, but I like it.
I bought a pretty white gardenia on etsy today: I will prob just glue it on top of the tulle.
Now I just need to decide if I should use the tulle or get some netting, I like the wider openings in netting and its more retro to me.
Anyone else doing birdcage veils DIY style? Suggestions or opinions?
Thanks!
