Do you collect tickets, some small souvenirs, postcards etc from the trips? Are they just lying around somewhere and you don't know what to do with them, but you can't throw them away? I feel ya!
I had a similar situation. I always collect some small "memories" and buy some souvenirs from trips, so I can look at them and remember. But, it can also be a struggle. Have you ever bought a souvenir which is just a place for dust? Yeah? I tended to do that earlier, now I try to buy only useful stuff. But I still have some old souvenirs (dust collectors).
And I decided to find a new way for them, how I can store them or use, so they will not be that useless. Or at least to store them in a nice place, so I would want to open them more often. Let's DIY!
