This is something anyone can do.  You may find that you have some wall space where you want to set something on the floor but there is not enough room.  Take an oblong canvas and paint a vase on it. Hang it low as to appear that it is just sitting there.  You can also have other objects instead. Perhaps a cat or a fence with flowers in front of it. There is no limit as to what you can do.  I like to use plaster compounds before painting to add dimension, character and designs.  Even if you are not an artist you can make an oblong, round, square or rectangular shape on a separate piece of paper creating a pattern to make a vase. Don't let the word "artist" stop you from acting on your creative ideas.  Give it a try.  You may surprise yourself.
