There are a variety of Dr. Seuss crafts and activities available in various books and websites. Some of the crafts are Dr. Seuss cat-in-the-hat hat, Horton hears a who craft, green eggs and ham placemat, Dr. Seuss doorknob hangers, Dr. Seuss medicine cabinet, and make a colored bookmark.

The easiest among the Dr. Seuss crafts is Dr. Seuss' Cat-in-the-Hat hat. It is a wearable paper hat; if you wear this, you will look like Dr. Seuss' Cat-in-the-Hat. The materials required to make this hat are construction paper (red and white), glue, poster board, and tape or stapler. First, cut a piece of white construction paper into strips that are about 2˛ × 8.5˛. Then cut a two-inch strip from the poster board that is as lengthy as you want to fit your head. Paste few white strips onto a piece of red construction paper. Try to keep equal spaces between strips, and leave nearly two inches of red at the bottom edge hence you can cut it to appear like a brim. Allow the glue dry for few minutes. Once it is dry, cut it into a hat-like shape. Glue or staple the bottommost center of the hat onto the poster board strip's center. Once you have attached the hat to the band, attach the band strip's ends together using tape or stapler to fit closely around your forehead.

Horton Hears a Who Craft is simple pink clover that looks like the one Horton is holding in the movie. You can also make this craft easily. To make this clover craft, first, take a green-colored pencil and paste a pink pompon to at the tail end of the pencil. Then paste a tiny white pompon onto the pink pompon and let it dry completely. Now the clover is ready!
