I saw this on another site where they used lace and decoupaged it to a number of different glass bowls and plates. I loved the way it looked so I tried it on a plain clear large mug. It was super easy. Check on Urban Comfort for all the details on how its done.
All you need is some Mod Podge, Lace and a glass bowl that you would like to spruce up.
And Mod Podge the lace to the bowl.
I used mine as a candle.
Above are examples from Urban Comforts.
