Soapmaking is an art of beautiful alchemy in the hands of the Spinster Sisters — in reality not a pair of siblings, but just one woman, Kelly Perkins, who was determined to school herself in the basics of the craft in search of a better, more natural bar of soap. Over the years, her line has expanded to include dozens of variations on the basic tool of cleanliness, as well as lotions, shaving products, scrubs and other products — all made from simple, raw ingredients and conscientiously packaged — that have been available for years at selected shops across the nation and locally at artisan markets. Since last spring, the faithful also have been able to flock to the brick-and-mortar flagship, Spinster Sisters Microsoapery, in downtown Golden. Make the pilgrimage, and clean up your act.
