how to host a tiny tea party:

first send out the tiny invitations.
then start with tiny take out boxes for party favors:
 fill them with tiny treasures:
 like a tiny puzzle eraser:
 and a teeny tiny pencil:
(also tiny bubbles and a tiny pack of smarties)
 make a tiny sign to welcome your tiny guests:
 be sure to hang a big magnifying lens
so they can read the tiny sign.
 decorate with as many tiny decorations that you can think of:
like tiny balloons and tiny jars for tea light candles:
hang water balloons to mimic real balloons.
and make tiny pompoms.
fill bowls with tiny food:
(blueberries, cherries, oyster crackers,
mini marshmallows, mini gold fish, baby carrots, etc.)
make a tiny little birthday cake,
mini cupcakes, mini brownies, mini sandwiches and mini hotdogs.

make a tiny little banner for the tiny little birthday cake:
fill tiny pinatas (minatas!)
miniature carnations for the birthday girl:
 give your little brother a huge magnifying lens.
(along with the other invited guests,
so they can see everything.)
 invite your big brothers to be mini waiters.
(they just might end up being the hit of the party!)
play mini games, like a mini art contest, 
the minatas, and mini kick ball.

and last,
expect BIG smiles!
