Everyone loves games. Everyone!
Paper and pencil games are a lot of fun, because they give the entire party a chance to see what others have written. It is a more concrete way to prove who has won.
There are a variety of games available, and you have to be prepared to play each one. First of all, you will need the games themselves. You will also need a place to play the games. You might plan on playing the games while your guests are all seated at a table, either before or after eating. This gives your guests something substantial to write upon. If your guests are all seated around an area in chairs, without a table nearby, then you might want to consider providing your guests with clipboards, or another writing surface.
You will also need pens. You can go with a box of stick pens, they really just need to be able to write. But you can also go bigger. If you have a star theme, why not look online and pick up a box of star pens? There are pens to go with almost any theme from flowers to tiny plush animals. You can allow the guests to keep the pens as an additional favor.
Speaking of favors, be sure to stock up on small gifts to hand out to the winners of each of the games. They don’t have to be big, just something that the guests will enjoy. You can also tie the prizes into the theme of the shower. Throwing a carnival theme? Why not hand out boxes of kettle corn? If you have a classically floral look, consider handing out small pots of violets, or freshly wrapped bouquets to take home.
