finger painting is sooo not just for kids. there are beautiful lines, textures, and color blends that you can get with your fingers which no brush or tool can match. circles, streaks, arcs, dabs, taps...i'm here to tell ya, do not fear paint under your nails.
acrylic paints and mediums are water-based and non-toxic; they can be scrubbed off your skin and nails with a little soap and water. even if your hands are stained for a day or two, wear your colors proudly...we're artists!
