I love a vintage hat with a veil. I especially like the veil hats that are simply veil with a bit of a bow or flower. Those look great arranged atop my hairdo and pinned in place with a flower. Sometimes when I find a new veil hat or unpack one that's been in storage I find the veil is wrinkled and needs to be freshened up. The fix is fairly simple - I use a tea kettle or a steamer. But recently I came across Emily's Vintage Visions Blog and she has an informative entry about steaming veils and fabric flowers along with clear pictures and instructions. I like her use of a steam iron - I'm going to try that.
