As you can see by the example art, there are many variations that you can use with this pattern.
Tips to keep the buckle ‘floating’ above the rest of the pattern. Make sure that none of the lines outside the buckle match up with the corners of the buckle.
Want the floating illusion to be stronger? The stronger the contrast between the buckle and the underlying pattern, the stronger the illusion.
Darken the outside lines on one side of the buckle and on the bottom. Shade one side of the buckle
and the bottom (See my pattern “Diaglyph“, for an example).
If you do use a pattern within the buckle, keep it simple. Simpler and more open than the pattern(s)
in the background.
