Rainbow Poplar refers to a designation of yellow poplar that has been mineral stained. The resulting mineral stained wood exhibits a variety of colors ranging from green, purple, black, red, etc. It is this distinct variety of colors that turns an otherwise oridnary piece of Poplar into the intriguing Rainbow Poplar. Poplar is very easy to work in almost all regards and one of Poplar’s only downsides is its softness. Due to its low density, Poplar can sometimes leave fuzzy surfaces and edges: especially during shaping or sanding. Sanding to finer grits of sandpaper may be necessary to obtain a smooth surface.
