Decide what size ornament you want to make and transfer the corresponding triangle and circle patterns to a piece of heavy card stock or plastic (coffee can lids work well for this). A 1 ½ inch circle makes an ornament that is approximately 3 inches in diameter.

Using your circle pattern as a guide, cut 20 circles from old Christmas cards. If you can center designs in the center of the circles that is best.

Place the triangle pattern in the middle of one of the circles (right side up) and fold the sides of the circle in around the triangle as shown:

Do this for each of the 20 circles.

Arrange the tabs so that they stand straight up.

Choose five of the folded circles and glue one tab from the first circle to a tab from the second circle:

Continue glueing tabs until all five circles are glued together:

They should be arranged like this with the tabs sticking up:

When you glue the last two sides together it will form a dome. This is the bottom of the ornament.

To form the middle of the ornament, select 5 circles and glue them together as follows:

Glue a to b to form a ring and glue it to the bottom of the ornament matching the tabs as you go.

Form the top of the ornament just like the bottom but before gluing the last two pieces together, remember to attach the ends of a piece of colorful string to hang the ornament by. Bring the loop to the outside and glue the top together.

Line up the tabs on the top with the tabs on the middle and glue them together to complete the ornament. For a sparkly effect, you can run a line of glue along the edges of each of the tabs, then dip them in glitter.
