Scrunch plastic grocery bags length-wise and tie off in 4 or 5 places. Cut the top of the bag, then cut just below each place that the bag was tied off. Add a pipe-cleaner or stick "stem" and secure with florist tape. Add pom-pom center. Swish flower petals lightly into tacky glue and then dip into glitter.
Place in glass jar, an old vase that has been donated, or inexpensive vases from the dollar store. Add greens if you have them.
