Homemade 100 Days of School Shirt Creations
There’s nothing quite like the pride a child feels when wearing something they’ve made themselves. My youngest, with her adorable gap-toothed smile, was incredibly proud of the shirt she crafted using just a plain top and some puffy paint. This approach proves that you don’t need to spend a fortune to make this day special and celebrate the school year’s progress. Imagine a white shirt adorned with vibrant polka dots made from Kool-Aid paint – a simple yet incredibly effective idea!
To build anticipation, you could even print out a printable monthly calendar at the start of the year and have your child mark off each day, counting down to this fun milestone. The joy of reaching the 100th day will be amplified! The shirt featured in the picture below is one we created, showcasing how affordable and impactful these DIY projects can be. We’ve also gathered a few other fantastic ideas from our creative friends that we know you’ll love. 😉

Our featured design, pictured above, utilized a simple tank top as a canvas for 100 puffy paint dots. This activity isn’t just about decoration; it’s a fantastic hands-on way to practice counting together! Beyond dots, consider using 100 tally marks or check marks across the shirt for a unique visual. While we didn’t have enough googly eyes on hand for that particular design, they are a wonderfully whimsical option for many other projects. The beauty of these homemade shirts lies in their simplicity and the opportunity they provide for interactive learning and creative expression.
100 Things T-Shirt: Fun with Edibles and Buttons
Another wonderfully engaging idea involves using edible items like Cheerios or colorful fruit loops. This craft not only produces a charming shirt but also allows your child to get more involved in the creation process by stringing the items themselves. Imagine them carefully threading 100 pieces of cereal onto a string, which can then be attached to the shirt or worn as a celebratory necklace! The best part? They might even enjoy a snack afterward. You could even add a playful message like “I Survived 100 Days!” on the front using fabric markers to complete the look.
- If you don’t have these specific cereals at home but love the necklace concept, consider using buttons instead. Buttons offer a durable and colorful alternative that’s just as easy for little hands to manipulate.
This button-themed project is an excellent craft for promoting fine motor skills and independent creation. Many sewing enthusiasts have containers of spare buttons, making this a truly resourceful and charming idea. Utilizing materials you already have around the house is a fantastic way to keep costs down and encourage creative problem-solving.

100th Day of School Ideas: Felt, Stickers, and More!
Here’s a wonderfully cute and tactile idea using felt and stickers! Start with a plain t-shirt and a contrasting piece of felt. Your child can then count as they carefully place 100 stickers onto the felt or directly onto the shirt. Stars, hearts, or simple round stickers all work beautifully. For the number “100” itself, you could use iron-on patches that often come with adhesive backing, eliminating the need for actual ironing. Alternatively, a permanent Sharpie marker can be used to boldly draw the #100, providing a quick and effective solution.
For those last-minute inspirations, consider unconventional items! If you have a generous supply, band-aids can be humorously scattered across the front and back of a shirt. Another fantastic and affordable option is pom-poms. You can often find large bags of small pom-poms at craft stores or dollar stores for very little cost. Kids love the soft texture, and gluing 100 of them onto a shirt is a fun, sensory activity.

How to Decorate a 100th Day of School T-Shirt Creatively
Looking for a truly unique and engaging activity for a 100 days of school shirt? Encourage your child to write 100 words all over a plain white t-shirt. Using a fine-tip permanent marker, they can write small words that hold meaning for them – perhaps all the spelling words they’ve learned so far, the names of their friends, or 100 things they love about school. This idea is not only a fantastic academic review but also creates a deeply personal and meaningful garment.
- For a guaranteed hit, embrace humor with googly eyes! Draw a silly monster, an alien, or a funny character on a shirt with a Sharpie. Then, glue on 100 googly eyes – large, small, or mixed sizes – for a truly eye-catching and hilarious shirt that will surely be a topic of conversation! This encourages both drawing skills and counting.
- Another fun idea is to use 100 fingerprints. Dip your child’s finger in fabric paint and have them press 100 prints onto the shirt. Each print can be a different color, or they can even draw small faces on each fingerprint after it dries.

100 Days of School Shirt Ideas for Kindergarteners and Beyond
- Foam stickers on a shirt are an excellent choice, especially for younger children in kindergarten, as they are easy to peel and stick. Keep an eye out after major holidays at craft stores or dollar stores; you’ll often find containers overflowing with foam cut-outs in various shapes and themes.
- These stickers typically come with an adhesive back and are incredibly inexpensive. Grab a few batches throughout the year and save them for this special occasion. Then, let your child enjoy the simple satisfaction of sticking 100 shapes onto a plain t-shirt. It’s a low-mess, high-engagement activity perfect for little ones.
- For a more structured approach, use 10 sets of 10 stickers, helping them practice counting by tens.
It’s amazing how quickly 100 days can fly by for our little learners! If you ask them for ideas to celebrate, their imaginations often run wild. My own daughter once suggested filling a gumball machine with treats to share with her class. While that would have been incredibly creative and a definite hit, my goal was to utilize items we already had at home. The essence of these projects is about using what’s available to foster creativity, not about elaborate purchases.

100th Day of School Celebration: Unique and Resourceful Ideas
- A simple yet charming idea involves using beads and safety pins. If you happen to have some beads and safety pins, your child can engage in this creative and tactile activity.
- The goal is to attach a total of 100 beads. They can string several beads onto individual safety pins, then attach these pins to the shirt. Alternatively, they can string beads to create a necklace that hangs over the shirt, making a beautiful and countable decoration. This is fantastic for developing fine motor skills and pattern recognition.
My overarching suggestion for all these projects is to always start by looking at home. Find a plain t-shirt that you don’t mind potentially getting messy or permanently altered. Then, embark on a scavenger hunt around the house for items you might have in quantities of 100. Don’t feel limited to a single type of item; a themed approach can be even more fun! Think about different colors of beads, various shapes of pasta with holes (like ditalini or penne), or even small toy figures if you have a collection. The possibilities are truly endless when you approach it with a creative and resourceful mindset. The most important thing is the shared experience and the joy your child will get from their unique creation.
General Tips for a Successful 100 Days Shirt Project:
- Pre-wash the Shirt: Always wash and dry the t-shirt before decorating to prevent shrinking and ensure better adhesion of materials.
- Protect Your Workspace: Lay down newspaper, cardboard, or a plastic tablecloth to protect your table from paint or glue. Place a piece of cardboard inside the shirt to prevent paint from bleeding through to the back.
- Involve Your Child: Let your child take the lead as much as possible. This is their shirt and their celebration! Guide them but allow for their unique artistic expression.
- Allow Ample Drying Time: Especially with puffy paint, fabric glue, or Kool-Aid paint, ensure the shirt is completely dry before handling or wearing.
- Consider Longevity: If you want the shirt to be a keepsake, opt for permanent fabric paints, markers, and strong fabric glue. For a one-day wear, less permanent options are fine.
- Safety First: When using small items like beads or buttons, supervise younger children closely to prevent choking hazards.


Celebrating the 100th day of school with a homemade shirt is more than just a craft project; it’s an opportunity to create lasting memories, foster creativity, and acknowledge your child’s incredible journey of learning. Whether you choose puffy paint, cereal, stickers, or googly eyes, the joy of making something together will shine through. We hope these diverse and budget-friendly 100 days of school shirt ideas inspire you and your child to craft a truly unforgettable garment for this special school milestone!
