An upholstery layer of a vehicle interior panel includes an airbag tear seam formed as a plurality of blind cuts arranged along a tear seam pattern. Each one of the blind cuts is formed by laser material removal at a plurality of locations along the pattern. Laser energy is delivered to the upholstery layer in a series of ultra-short pulses to form the blind cuts, which are formed in the upholstery layer while separate from a substrate of the panel. This technique is particularly useful with leather upholstery materials, in which non-visible airbag tear seams have been proven difficult to form.
