Update: of course I started buying stuff!
Got my first washi tape (as shared in another thread) and 3 sheets of stickers.
Stickers are almost running out, but reading a thread here about creating your own stamps (the physical ones with ink), I remembered: I have stamps! to decorate the log book of fellow divers!
More fun to add to the back of my postcard!
Edit: I already had great taste more than 10 years ago, look how cute!
