Invites- The first idea is to take a plastic shovel. Print out your invites and put the shovel in a plastic bag. Fill with candy, small rocks, etc. Another Idea is to take and print out your invite. Roll it up and tie it with a string. Put it inside of a bottle with a cork. You could also scorch the edges of the invite to make it look "Beachy".
Decorations- To start off we took a red frisbee. We printed out a sign that said "Happy Birthday ---------------" and pasted it in the middle of the frisbee. We then took some small umbrellas and pasted them all around the frisbee. Tie a sting on back to hang and done!
We also made styrofoam palm trees that we put around the house. We cut out monkeys out of construction paper and hung them around. If it is outside you could put some sand on a tarp. Or have sand boxes avaible.
Food- Here are some pictures of food ideas.
