nails are a fantastic record keeper of a thickness and layers previously there.
each offers a measuring stick and regional sampler of the stripped building material, having undergone a palatable deformation as the metal sliced through wood, linoleum, asphalt, shingles, or sheathing.
particularly on a sun streaked surface, these skeletons strike shadows activating the newly thinned membrane.
functionally, these remanent nails engage the floor, roof, and wall differently. as a surface to walk on, the nails interrupt, restrict, puncture and striate a previously smooth floor. along the wall, the nails dictate an offset distance or directs where something is to rest and lean. along the wall, nails also offer a hook from which to hang things, as a pegboard does or the shaker peg rail banding each room. nails extruding up from a roof gather, collect and sift, interrupting any shedding generated from the pitch.
