All you need is colored tissue paper, scissors, and wire to make these dahlia-like pom-poms that seem to float over the the table. Use different sizes of paper and trim the ends at differing angles to create variation in the flowers.
These decorations really layer on the style. Any pale-colored paper lantern can be covered with tissue circles (buy them precut -- no scissors required) for a charming fluttery finish. They may look intricate, but it takes only half an hour to make one.
