Use one large white poster board and title it "Roses are red, Violets are blue..." at the top center. Cut one large heart out of construction paper and glue to the bottom corner of the poster board so that it forms a pocket to hold markers, smaller hearts and scotch tape. Cut smaller hearts out of construction paper ~ these should be big enough so that you can write a line or two on them. Place these in the larger heart pocket. When guests arrive tell them to take a heart and finish the next two lines of the poem. Then they stick their heart to the board with scotch tape. Try and fill the board with original and funny ideas for this very old love poem.
