Draw your pattern
Trace or draw the face pattern onto a piece of folded green paper, as shown.
Cut out the frog face
Keeping the paper folded in half, cut out the frog face. Cut out the mouth and use a paper punch to make the nostrils.
Cut out a shape for the frog's eye
With the face still folded in half, fold along line A. Cut out the eye.
Fold along lines B and C
To make the folds crisper, press down along them with a ruler or with your scissor handles.
Open the folds to reveal a frog
Open up your frog face and gently pull the lower lip, nose, and eyelids forward so they look like those in the photo. Push all the other folds back. If you want, decorate your frog. (It's easier now than when it's glued into the card.)
Glue the frog to a card
Fold an 8 1/2 x 11" piece of paper in half. Turn your frog over and dab glue on one half of the face (see pattern). Line up the bottom point of the face with the fold of the card and glue this one side in place. Flatten the face, dab glue on the other side, and press the card closed.
Make the frog tongue
Trace or draw the tongue pattern on a piece of folded red paper. Cut out. Then fold back the tabs at the dotted lines. Glue the two pieces of the tongue together as far back as the dotted lines. Then glue the tabs inside the frog's mouth, one tab on either side of the card's fold.
