I can't believe six weeks are almost over but I'm really looking forward to see my family and my friends again! The time her was/is awesome and I'm sure I'll come back here sometime. I did this DIY a while ago, so this is one of my "prepared posts" while im in Canada although I'm almost back home.
You just need an old shirt, a scissors, textil colors, tape and a brush. The shirt I used had really thight long sleeves, so I cut the sleeves off and cut them in half. Then I sewed them back together to a short bigger sleeve. But if you already have a shirt with loose sleeves you can actually skip the first 7 steps. Now you have to put the tape on your shirt and fill in the number and the stripes with paint. Let it dry and that's it!
