Who Should Come to the Party?

It can be difficult to decide who to invite to the party – it can be tempting to invite everyone you know! But, it can be a bit overwhelming to have too many friends at the party, and can lead to tears and tantrums. It also depends on the venue – if the party will be held at home, there might be limited space. However, if you go for a party place, there might be a minimum number of guests, in which case you might need to invite more friends.

Once you’ve decided who to invite to the party, you’ll need to choose some invites which match the theme. Here are some ideas.
