Leather edges need to be finished after cutting, in order to strengthen the edge and protect the leather inside. Usually, burnishing is done to seal the edge. For additional protection, and mainly visual appeal, edge paint can be applied.
Edge paint covers the edges of leather goods and items, sealing the inside of the edge, and providing a pleasant finish to look at once it dries. Some leather crafters use this to create contrast with the leather piece. Others use it to blend the edges in. Edge paint are available in a wide variety of colors.
