Although of different styles and hundreds of years old, these repeating ornaments are still usable. All four ornaments are very easy to draw, especially if you use some 2D CAD or vector software. It is enough to draw a grid formed of parallel lines, oblique or rectangular. Draw the repeating motif (core) in one grid cell, and then copy it to all other grid cells. When you have a surface that needs to be decorated with a repeating ornament, it is very important to determine the grid dimensions. If we decorate it with a repeating ornament whereby the core, i.e., the grid cell is too large or too small, a very bad visual effect will be obtained.
All 4 repeating ornaments have been precisely drawn in Inkscape vector software, they are simple in appearance and can be applied in many ways. As always when we draw a repeating ornament within the file is the segment of ornament with which you can draw an ornament of any size.
