Nothing tastes better in the summer than lemon ice water. This is a fun way to fancy it up for your summertime events.
Start with some lemons,
slice 'em up,
fill the glasses with ice, water and a wedge of lemon,
place a round slice right on top and a straw through the center.
It flavors the water perfectly and gives a really pretty uniform look to the glasses.
So inexpensive, but still looks like you've prepared a special drink for your guests.
