I really like the background of two fabrics. The white blossoms stand out against the green print, and the green of the shamrocks and the letters really pop on the white. Flat buttons for the centers of the blossom would be fine, but I like the way that the three sequins on each blossom add sparkle and a festive air.
I hope you find your very own special rainbow this year.
