How to Make Your Own 100 Days of School T-Shirt


These 100 days t-shirts are so much fun to make. The best part is you can modify any great idea to make it with the materials you have on hand. Here are the most common materials that are used that you might already own. If not, your local craft store will have them:

  • t shirt (white t-shirts or colored t-shirts will work)
  • fabric paint
  • fabric markers
  • fabric glue
  • hot glue gun
  • piece of cardboard – Use it to slide underneath the front of the shirt so your glue or paint doesn’t bleed through.


  1. With any of the 100 days of school ideas below, you can write the saying on the shirt with markers or paint.
  2. Then, glue the items around the words.
  3. If you know it will be a big deal to your child if an item falls off, make sure to use enough glue. Once it dries, have your child try it on for 20 minutes and see if any need more glue. You can also give them a small ziplock to put in their pocket to keep any items that fall off so they will still technically have 100.
