Teen DD has no interest in posters. She has various coloured lights, hippy scarves & fake vines plants hanging everywhere and incense / candles which she is banned from lighting 
. She doesn’t have any celebrity crushes or heroes, really. She loves ‘designing’ her room, though.
Teen DS has a massive framed Breaking Bad poster 🤔, some Marvel posters, and a print of a 90s rapper he likes. The difference is they’re expensive posters, framed and hung.
Me and my sister shared a room and our walls were covered in scrappy Smash Hits pull out posters. I was Madonna-obsessed and would cut out every photo of her I could get my hands on in magazines and make big collages that I stuck to my wall with sellotape (my Mum was NOT impressed).
Later in my teens I had rave flyers all over one wall and a life sized poster of the US R&B boyband Jodeci on my other wall. I used to kiss my two favourite members,
K-Ci and Devante, goodnight every night 😂
We had to make do and mend in those days. My mum wasn’t going to fork out for picture frames or any fancy Knick knacks.
