 Make a collage and put it on the wall? 

 I have a drawer full of "souvenir money" from international trips 🤣  

 Looks flammable? 

 toilet paper, kindling for a fire, mulch for the garden, so many uses!  It has intrinsic value after all... 

 Es la que mi sobrinita tiene en su cartera. Segun ella es rica😂🤣 

 I keep leftover currency from trips as souvenirs, lol. I tape them into my journal as a memory. 

 At least it's pretty paper, arts and crafts? 

 Lighting Up cigars 😏
