Not crazy about the polka dots but cute idea! To make Tipsy Pots, you simply get whatever length of rebar you want (allowing for or more to be IN the ground). Then just slip the terra cotta pots over the rebar and and "tip" them as you go up.
Maybe an up cycle idea for all those used formula tins - Tin can vertical plant hanger and rustic painted wooden screen door. Love the screen door as a decorative element with potted plants surrounding.
