Wrap one colander handle tightly with a half-yard of twine, pushing pieces together as you go to avoid gaps. Once covered, tie off and add a dab of glue to secure. Knot a yard of twine at each end of the handle. Repeat entire process with opposite handle. Next, line the colander with sheet moss and fill with potting soil and seasonal plants. (We used ferns and pansies.) Tie four lengths of twine together and hang.
