Wedding Rehearsal Dinner

I am throwing my sister-in-laws rehersal dinner. For centerpieces I got an idea from this months I believe it is womens day magazine, Micheals craft store has these small vase for i think it is 79 cents put the water in the vase and then add food coloring to color the water then add 1 to 2 of the fresh sunflowers they look very pretty. Then we are doing like a taco bar with flower and corn tortillas, tostada shells taco meat, carne asda chesses,lettuce tomatoe, sour cream,cilantro,onions, thres leche cake and frech homemade sangria. I am also doign a pinata for the adults with some $5 gift cards thrown in there, magnetic frames that will not brake and of cours esome hard candy (since it is summer and I dont want chocolate to melt) In the brake ground I am going to play some Mexican busic I have the Ricky martin spanich CD and some others .
