100 Days of School Cartoon: Back to School PNG Images for Shirts, Tumblers

This 100 Days of School cartoon sheet is a set of ten separate back to school designs, delivered as PNG files with transparent backgrounds for shirts, tumblers, stickers and classroom signs. Each illustration uses bold lettering such as “100 DAYS OF SCHOOL,” “HAPPY” and “SCHOOL,” alongside red apples, pencils, rulers, a globe and a disco ball. The palette is built from red, yellow, blue, green and orange, with pink, black and white for accents, so the colours stand out on light and dark fabric alike. Several designs carry the line “of making the whole class SHIMMER,” which suits a 100th day celebration. The artwork has a playful, energetic feel that works well for elementary classrooms, where students, teachers and parents all want something cheerful to wear or display. Because each design is a separate image, you can pick the ones that fit your project and skip the rest.

Design breakdown

The sheet is a square grid of ten separate cartoon designs, each on a white background and supplied as PNG files with transparent backgrounds. Designs in this set include cartoon character figures in bright shapes, red apples with pencils, a globe with stars and clouds, and a set with brick blocks, question-mark blocks, coins and small mushrooms. Other designs show a disco ball with sparkles, race-kart shapes, a wooden desk or shelf with a pencil cup, and hearts with smiley faces. The palette uses red, yellow, blue, green, orange, pink, black and white. The artwork is built in 6 layers and is intended for cutting with a fine-detail setup, so cut it at 4 inches or larger for the small pieces to stay intact.
