Pebbles and shoes, it turns out, are quite compatible things, if done, as this photo suggests. Filling a suitable tray with pebbles, you can get a beautiful shoe mat. Excess moisture will drain onto the pebbles, remaining in the pan. Puddles of dirty water on such a rug will not be noticeable, unlike a smooth floor.
You can do a lot of pebbles in general. In some places this natural material is available, the only problem is the imagination of the owners. Using pebbles in this way, we get, in addition to neat shoes, also a non-standard decor.
