For my daughter's first birthday we went all out with the theme. We chose polka dots so we did everything round from our food choices (round cutout sandwiches, nila wafers, cheerios etc.) to our decorations. We wanted a custom theme that no one else would have. I designed banners and cupcake toppers as well as the cake to correspond with the colors and theme. As favors I gave out M+M's in pink and green for our older guests and hand painted sippy cups for our one year old friends. We received so many compliments, and everything turned out fabulous!
