My brother had a hoodie with the same headphones design on it, but it was too small for me otherwise I would've stolen it from him, so had to make do with this design on my own t-shirt instead!
Here are my things gathered together, including a paint pallete and snazzy mat my mum insisted i use to protect her table underneath.
Also on here you can see are two paper templates I used, traced from my brother's hoody.
Oh! Don't forget to put some cardboard (i used some from a cereal box) in the t shirt, so the paint doesnt seep through the layers.
