Vase cover

When you have a cylinder vase with a big mouth but you get only one flower to be put into it, the picture is not so nice.

Well, you can buy more flowers, but the whole picture becomes noisy. Or you can give up your old favorite vase for a new smaller one, but I guess it is not the best choice.

My option is to put a cover on the mouth of the vase, so as to make a balance between them.

The cover looks like a wave, the right part of it is higher than the surface of the vase mouth, while the left sinks into the vase. The flower could be put through the hole.

For dimension of the vase i used, its mouth has an outer diameter of 122mm and an inner diameter of 107mm.
