Back in the 70's I was one of the many using the fad of lace painting cars and motorbike tanks. (very girlie these days but it was popular back then)
The method was to place the lace over the area to be painted and spray paint over the lace, then lift it off when the paint dried. Same method as any custom painting.
Many people used lace table cloths to spray through, but these days you can buy lace in rolls at places like Spotlight.
As an example, here is a pic of a pushbike frame using the lace stencil idea
