When you send invitations to your guests, then you have to set a tone. Have your invitations inform guests about the details of the party and also provide information about the theme of your party later. You can get an invitation at a party supply store or would be more interesting if you make your own invitations at home and provide the creativity. For butterfly party theme, you can match the invitations.
Provide photographs of butterflies with high resolution on your invitation. Then print it yourself if you have a photo printer. After your photo prints, you can write the party details on the back of the invitation and photograph butterflies can you paste on the envelope.
Another idea you can try for butterfly invitations is to use stamps to cover the plain invitations with butterflies. You can get stamps butterflies at the craft store. If you can not find the butterfly stamps, you can make a stamp out of a potato carving the shape of a butterfly. Dip the potato into ink prints by giving a different color.
You not only can use the butterfly as a decoration, but you can also send invitations to the shape of a butterfly. You can find pre-cut paper or a butterfly-shaped paper and write your party details and send them to your guests.
