The invite is a bowling ball and it just has the info. 4 the party on it. pretty simple.
Decor:
depends on where u have the party...but bowling themed stuff is always good.
Food:
eather pizza or chicken is always good
Music:
whatever u want
Highlight:
what u do is see if u can rent out a place at a bowling ally. usually, u can hold the 1st 10 lanes or so...depending on how many people u have. u have people write in there high shore and u give a prize to the person with the highest score of the day. this gives people something to do all day so that they wont get bored. and other people who cant bowl can sit and watch and still have somethign to do.
