I just adore this watermelon theme party that I threw for my son, for an end of the summer bash with his neighborhood friends. From the invitation to the sweets, the decor to the favors, every last touch was watermelon themed in pink and green. It all starts with the perfect invitation. I designed this invitation on photo shop and printed it out on card stock. My son went around to all his little friends passing them out, and that was one of the high lights for him! Four years old is such a fun age!
