Make sure the dye you chose is leather specific, as this will give you the most natural and realistic results.
If there are any areas that you do not want dyed on the leather furniture, such as a reclining handle, push buttons or decorative tacks, etc, be sure to cover them using masking tape and/or paper towels to prevent over-spray.
You may use other products such as acetone but these are extremely erosive and too much can actually cause a chemical burn and severely weaken the leather!
