These are the left over warp threads from industrial looms after a run has finished. They are 100% either bleached or natural cotton. While cotton waste is used for the stuffing for French polishing rubbers, it is also invaluable as applicator material for wax on venetian plasters. The advantage of cotton waste is that it puts on the minimal layer of wax to help avoid swirl marks when the wax is polished. Unlike cotton rags or cheese cloth it will not get clogged up with wax. Cotton waste can be continually pulled apart to keep the wax application even and as light as possible. Cotton waste is also very useful for evenly applying wood stains and cutting down the problem of lap marks.
