The frosted seaglass is gorgeous. While there is a great selection of Frosted Glass Vases/Bottles to Buy, you can DIY this look with Seaglass Spray Paint, or as featured below, with paint.
Sand and Sisal's Glass Bottles were painted with glass paint.
The look of these seaglass colored bottles was created with Mod Podge, a few drops of food coloring and some dish soap, all mixed up in a bowl. By Home Deco 50.
Twigg Studio used regular Elmer's instead of Mod Podge to paint their glass bottles.
