Origami corner bookmarks are one of the quickest paper crafts for kids: they use one square of paper, no special tools, and create a useful little gift in about five minutes. This Bearabbit Studio tutorial is designed for preschoolers, elementary students, parents, and teachers who want a simple screen-free project.Materials• One 6 x 6 inch square of paper• Pencil and ruler• Safety scissors• Glue stick• Markers, crayons, or stickersPrepare the paperStart with a clean square. If you are using printer paper, measure a 6-inch strip, cut it, and save the remaining paper for decorations. Thicker paper makes a sturdier bookmark, while lightweight paper is easiest for young folders.Step 1: Fold the squarePlace the paper like a diamond. Fold the bottom corner up to meet the top corner, making a triangle. Press the crease firmly with a fingernail or craft stick.Step 2: Bring the corners togetherFold the left corner up to the top point. Then fold the right corner up to the top point. Unfold both folds so the crease lines remain.Step 3: Create the pocketFold only the top layer of the top point down toward the bottom edge. This creates the front flap that will hold the page corner.Step 4: Fold the sides inwardBring the left corner up again and tuck its point under the front flap. Repeat on the right. Smooth every edge so the pocket stays flat.Step 5: Strengthen the foldsRun your finger along the two side creases and the top edge. Add a small amount of glue under each tucked point if the bookmark will be used every day.Step 6: DecorateTurn the simple pocket into a monster, bear, rabbit, fox, or cat. Add ears, teeth, whiskers, eyes, and a funny expression. For a Bearabbit, cut two rounded ears and draw a tiny nose. Keep decorations flat so the bookmark slides easily over a page.Customization ideasMake a rainbow set for a classroom reading corner. Use recycled magazine pages for colorful patterns. Add a name on the back for a party favor, or invite children to design a character that matches their favorite book. Older children can compare how the same square becomes a triangle, pocket, and finished three-dimensional corner.Teaching tipsUse washable markers and pre-cut squares for preschool groups. Ask children to identify the square, triangle, corners, and lines of symmetry. This activity also practices sequencing, fine-motor control, and careful listening.Free printable templateDownload the Bearabbit Studio printable template here: https://bearabbitprintables.com/3d-papercrafts/Safety noteAdults should supervise scissors and glue.
