Martha has several great party decor ideas as usual. I especially love the set up below and there is a tutorial for the decor on her website.
In fact last year The TomKat Studio was inspired by this party to design Cinco de Mayo printables and they are free to download on her website. I am so wishing I had time for a Cinco de Mayo party right now. There's nothing better than Mexican food.
And for those of you who are not familiar with the celebration, Cinco de Mayo (Spanish for "the fifth of May"), commemorates the Mexican army's victory over the French army at the Battle of Puebla in 1862. It is often confused with Mexican Independence Day, but that is actually not until September. In the United States Cinco de Mayo is mainly a day to celebrate Mexican heritage, culture, customs and FOOD! Oh, the food. Please pass the chips and salsa.
