The design you see in the picture is called ‘Rose Repeating Design’, and it is a typical example of how a simple design can be turned into a more complex one.
By analyzing its appearance, we can recognize that the design consists of only one motif made up of three identical crossed rose stems with leaves. If we draw an equilateral triangle, we will see that this motif can fit into it quite nicely. Now, if we rotate the equilateral triangle together with the motif 6 times around the upper top of the triangle, we will obtain a hexagonal design consisting of six identical rose motifs. By copying the hexagons next to each other, we can form this repeating design of the dimensions we desire. Also, there is another way to make this rose repeating design; place the motif in an equilateral triangle, copy it, rotate it 180 degrees, then lean it on the initial one, and in the end you will obtain two triangles next to each other, with the motifs inside of them. If we repeat this procedure, we will get a frieze design of a certain desired length. The repeating design from the picture is obtained by mirror copying (in relation to the upper or lower horizontal) of this frieze design and the newly created designs until it results in the design of desired dimensions.
