As the name of her studio—Tips And Toes By Anna—indicates, fingernails and toenails are Anna Marie Donaldson's specialty. Not only does she pamper them by offering exfoliating scrubs and soothing massages and hot towels, she ensures digits look their best. That means coating nails in OPI and other top-shelf polishes and adding detailed nail art that ranges from leopard-print, snowflake, or beach-scene designs to glitter and 3-D embellishments.
