Buy the premade cheesecake filling (in the cold section) hull strawberries and fill them with cheesecake filling (with a decorating bag) -- top with a blueberry... very easy and soooooo yummy! Carla 

A friend shared this idea with me....take a strawberry, dip in white chocolate but leave 1/3 of the red showing, then dip the bottom tip in blue sugar while chocolate is still wet. Patriotic berries. Tara 

I take red Jell-O in a bowl layered with while whip cream and blueberries. Christina 

And a great, last-minute patriotic activity for the kids too: 

I made a flag from paint stirs from Home Depot. painted them as a flag, glued them together and then glued on buttons in the appropriate colors of red, white and blue with a patriotic ribbon to hang it. It was fun to do and cheap! Anna
