Our colouring t-shirts are 50/50 cotton/polyester blend with a sublimation print. Which means it will last wash after wash! You choose whether your artwork stays permanent by using permanent fabric markers OR use washable markers and you can colour again after you wash it! Markers are sold separately through us or from your local craft supply store.
We recommend Crayola Fine Tip Fabric Markers because of their ease of use and quality of colour, but there are many different brands to choose from.
