Sailor's knot braid: four strand braid. 1) Divide hair into 4 sections and number them 1-4 from the left. 2) #1 over #2, #3 over #4. 3) #4 over #1. 4) Re-assign the numbers so that the section on the leftmost (originally #2) becomes #1. 5) Repeat from step 2.
Paint your nails with a base color and let them dry completely. Then, come back and paint a layer of another color on top, and before it dries, you dab pieces of wadded up saran wrap on top lightly, then top coat.
