Painting flowers for a decoration requires patience and preparation. However, when the task is finished, it will represent a beautiful depiction of nature. You may choose to paint flowers such as roses, irises or hyacinths. Painting either a single type of flower, or a mixture of different flowers will help you to perfect your technique and to understand how to better draw what you see. In order to paint flowers for a decoration, determine which types of flowers that you want to paint, obtain a sample of the flowers, sketch the flowers, paint the sketch with the main colour, add the other colours, and then analyse the painting and determine how to provide it with a more natural appearance.
Determine which type of flower that you want to paint. When painting flowers for a decoration, you may want to paint your favourite flower, or the favourite flower of your friend. If you are undecided about which flower to paint, then you can look at different flowers at the florist or online.
Obtain a sample of the flower that you are going to paint for a decoration. You can either choose to obtain a real sample, or you can use a picture of the flower as a sample. Using a real sample is recommended because analysing a natural sample can help you to paint a more realistic picture.
Sketch the flower on a piece of paper. Lightly draw the main shape of the flower in pencil. For example, if you are sketching a rose, then you will want to draw the spherical shape of the flower, the elongated stem, and the conical thorns that are present along the stem.
Paint the sketch of the flower with the main colour of the sample. For example, if you are painting a red rose, then red should be the first colour that you use for the flower. You can also paint the stem a deep shade of green, and use brown for the thorns.
Add the other colours to the painting of the flower. When painting a flower for a decoration, you will notice that the actual flower is not uniform in colour. For example, not all of the petals of the red rose will be the same shade of red. Analyse the sample, and add a deeper shade of red to the petals that have a deeper colour. You can do the same for the stem and the thorns.
Analyse your painting and decide on how to provide it with a more natural appearance. This often means that you will need to add various brush strokes to the flower to perfect it and to depict the different textures. For example, if the flower is smooth, then you can add brush strokes in which you do not lift the paint brush from the paper. If the flower is textured, then add choppy brush strokes. The portion of the flower that is closest to you should have thicker brush strokes than the portion of the flower that is farther away. This will help to provide a 3D quality to the painting.
