We are doing these!! They are made by Kate Aspen and come in "Mix & Mingle Key Lime Margarita Mix" and "Razzle Dazzle Raspberry Iced Tea Mix" and "Main Squeeze Lemonade Mix". We are actually doing the lemonade mix and trading the red umbrellas for orange because our colors are yellow and orange! You can find them as cheap as $2, depending on the # you need. They come in packs of six!
