A small caroling invitation made to look like a book used for caroling.
Copy some musical staffs onto the white piece of paper and add a few notes here and there.
Put the party details in the space where the lyrics would go.
Glue the white sheet to the inside of the construction paper and mail to your friends.

Readers' Digest caroling songs to print. There are 28 pages with popular songs for caroling that you can print out. I can't remember the exact number of songs as some of them do take two pages. Print out all of them or just a few of them and create a caroling book to use as an invitation. Put the party information on the inside cover of the book with instructions to bring the book along the night you go caroling.
When assembling the pages in the book, any song that has two pages should be put into the book facing each other as in the sample above.
Print out the songs that you want to sing.
Make sure your pages are in the correct order and paper punch holes into them.
Lay one of the pages with the holes in it over the construction paper as a guide for where to punch those holes. Construction paper is larger than the printer paper.
You can fasten the pages a couple of different ways, I show three different methods in the picture above.
The first method uses red ribbon and a simple bow, you would just tie a bow into each hole. It would be fun to tie a small bell onto the top one.
The second method is a brass paper fasteners, they're easy to use and inexpensive.
The third method uses half of a pipe cleaner per hole, just cut a pipe cleaner in half, insert through the hole and tie into a knot.
