Top grain leather - Hair side

The grain side refers to the smooth, grained surface facing the hair side (or the outside, if no hair is present) in leather. Each type of leather has a unique characteristic grain pattern. The pore density is much heavier on cow leather than on pig leather. The grain pattern can be changed by embossing and colouration. Even split leather can be coated in such a way that it appears like top grain leather.

The side of the skin facing the meat of the animal is called the flesh side.

Types of graining: fine pore leather - coarse pore leather - fine grain leather - coarse grain leather

The original grain pattern already differs on the same animal skin surface. In the middle of a skin, the leather is mostly fine-pored, and towards the edge it becomes more coarse-pored. The appearance of an even skin structure is often disrupted by deeper natural wrinkles.

On same skin: fine pored -> transition -> coarse pored.

The main grain is partially traversed by deeper natural folds.

When cutting, care must be taken that the grain pattern is chosen as symmetrically as possible.

Embossed leather

Grain side, but with embossing: furniture leather with distinctive pattern embossing. - Car leather (cow) with embossing of pig leather. - Crocodile embossing on cow leather.

Compressing and stretching leather grain

Sometimes the grain in the leather has become smoother due to tension or stretching. For smaller surfaces and areas, you can try to strengthen the grain by compressing it. The effect is not as lasting as with an embossing, but sometimes it is sufficient. Important! Do not stretch the leather again afterwards, otherwise the effect will be gone again immediately.

A leather grain can be locally reinforced by compressing.

There is also the opposite situation, that a grain is too strong and should be smoothed. In local areas, the leather surface can be pulled and stretched. As a result, the grain structure flattens out.
