Thanks a lot, @stephenkendal! I am really honoured to have you visit my blog. Glad to know that you like the t-shirts. Honestly, the idea of QR code, I got first from reading how you add the code to your flyers for #promo-uk. So, I figured that it would be nice to print it on the back of steemit branded t-shirts. Many thanks too for giving me a whole new idea of #promo-serbia. I should begin to use that tag soon.
