Q: What can be done to turn an ugly jar into a beautiful vase with lace trim like the one shown above?
A: Let it die and come back as a vase in the next life.
Hold on, actually Hong Kong Milk Design has a faster and simpler method - put a "cover" on it. But don't get the wrong idea, this cover is not what you're thinking of. The universal flower vase cover (Lace Vase) is made of rubber (yeah right, same material, still not what you thought), which has a certain degree of elasticity (evidence confirmed), allowing it to easily fit snugly over plastic bottles, glass jars, wine glasses, and many other containers of different sizes, transforming them into elegant vases within just a few seconds.
