Faux Painting 101: Crumple a rag, then roll it into a worm-like shape. Roll it down the painted or glazed wall surface for a subtle faux effect. For more drama, try adding the paint or glaze onto the rag itself before rolling on the wall. (Note: In this photo, shale blue was rag-rolled on top of a Baltic green base, then antique glaze was sponge-rolled over both.)
