DIY 100th Day of School Shirts Supplies

Before we start getting creative, we need the basics!

Here are a few items you may want to have on hand before you and your kiddo start diving into creating and DIYing the perfect 100th day of school shirt!

Blank shirt

Plain Boys Tee


Of course you can’t make a 100th day of school t-shirt without a blank canvas to work with. These tag less shirts come in a bunch of different colors!

Warmer option

Blank Sweatshirt


Since the 100th day of school often lands sometime in January or February, a long sleeve blank sweatshirt might be a warmer option.

Shirt decorating

Fabric Pens


Picking up a pack of fabric markers will take you a long way! These fabric markers have great reviews and come with SO many colors so you and your kids can really get creative!

Fabric Glue


I’d highly recommend grabbing actual fabric glue. If the shirts get dirty during the day and you want to preserve it, using actual fabric glue will be a lot better than hot glue for when it comes to washing it.

Puffy Fabric Paint


Puff paint is so under rated! Use fabric puffy paint for an easy way to not only draw/write but also add a 3-D pop!
