1. Buy a simple shirt. This one was on sale for 20 Dkr.
2. Find your scraps of yarn in the colours you like
3. Crochet small circles with two different colours. Weave in ends
4. Attach the circles to the shirt. I used my sewing machine for this part. Now you have a unique shirt and people will surely think that it costed a lot more than 20 Dkr. Enjoy!
