A bicycle in the country can be very useful, even if you can’t ride it for a long time. In this case, it can become a stylish decoration of the site. And if there are only spare parts left from it, wheels, for example, you can use them to decorate some boring wall, as in the photo.
Such shelves look stylish and original, and for their production, except for the wheels, you only need ropes and planks. The photo suggests a log cut in half along the length, you can do so. In any case, the shelves can be used as flower stands. But you can put something else on them so that the viewer's attention is attracted not by a bare wall or fence, but such crafts from old things.
