If the area is rough to the touch, or has burrs or snags that catch when moving your fingers across the area, then use 400 to 600 grit sand-paper to remove or reduce them. Then, using a palette knife, apply an even swipe of fill compound across the void, with the final goal being to fill the void to a level consistent with the surrounding leather. If the back side of the cut is accessible placing something solid and flat such as a CD case to press firmly against can help secure the edges together more easily. To completely fill the void, multiple swipes may be required. For best results, each swipe must be allowed to cure before applying subsequent fill compound.
You can either let the compound air-cure, which can take 10-30 minutes, depending on conditions and the amount of fill compound applied. Or, a hair-dryer on high can be used, but this tends to skin over the top of the fill compound, trapping moisture in the lower layers, and will represent as residual shrinkage after the repair is done, as the trapped moisture is slowly absorbed by the surrounding leather fibers.
The fastest and most reliable way is to position a lit 60-75 watt light bulb above the repair, at a height of about 3-4 inches. The bulb's radiant heat helps to evaporate the moisture quickly out of the fill compound without skinning over, or forcing it down into the lower layers. A bulb can cure a fairly deep swipe in 3-4 minutes. You can sand between swipes to eliminate burrs, and feather the edges of your swipes.
Dry sanding is preferable if there are no major ridges or burrs to remove. Dry sanding is used to remove grittiness. Wet-sanding is used to knock down high spots and remove ridges quickly. Do not over-saturate when wet-sanding. Lightly dampen the sandpaper with water, and blot, so as not to introduce too much moisture back into the filled area.
Alcohol wipes can be used to remove ridges, and feather the edges of the compound, as well. The solvent softens and reconstitutes the fill compound, helping to eliminate high spots or ridges as you rub across the problem areas.
Typically the next step is to apply the correct color to conceal the repaired area.

To fill sewing needle holes in thick leather, first clean the area around the holes to remove any debris. Then, use a leather filler or a mix of leather dye and adhesive to fill the holes, applying it with a small tool or toothpick for precision. Once the filler dries, you can sand it lightly for a smooth finish and apply a matching leather dye to blend it in. Finally, seal the area with a leather conditioner to restore suppleness.
You should make sure they stay supple and in good condition before the leather gets cracked or hard by regularly treating them with a good quality brand of leather conditioner.
