The Harry Potter Room...

this 1 is cool. :)

well which house do u like best for ex: griffindor the 벽 can be red and yellow 또는 당신 can do a darker shade of blue and get some harry potter fatheads (wall stickers) and some glow in the dark stars that stick to the 벽 happy decorating

색깔 in yellow, 주황색, 오렌지 and red could be appropriate. 당신 may either buy some Gryffindor stuff 또는 make them, for example. 또는 get inspired 의해 the movie Gryffindor Common Room. That is, if 당신 feel like belonging to that House. 당신 may choose another house, with another set of colours and props.

Depends on how extreme 당신 want to go.
4 walls, 4 houses - two thick stripes vertically. Red and Golden for Gryffindor, silver and green for Slytherin, etc. Black cover onto the 침대 with Hogwarts crest on. 당신 can also get posters of the crests for each walls. A HP posters, a Snitch hanged from the ceiling.

또는 당신 can select a house and go after that: leather stuff with some vintage 바탕화면 (gray background green pattern) with green border/dark yellow walls with red border and Gryffindor crest, red chair, carpet in Victorian style...

또는 당신 can go Great Hall style. Some matte color onto the 벽 (grayish brown) and paint candles in eye level and open sky onto the ceiling. 당신 can put the crests onto the walls and get HP style 시간 glasses (test tubes filled with colored sand). Posters, scarves, lava lamps (yellow and red ones).

또는 there's the Black style. Stylish 바탕화면 classical furniture Gryffindor and Hogwarts crest, Marauders poster, motorcycle poster, bikini girl poster (or pants guy if 당신 are a girl), family 나무, 트리 (poster 또는 a painted 나무, 트리 의해 your own lil hands with pictures of Bella, Malfoys etc above the names). And a name board onto your door like Regulus Arcturus Black. Dependant on how hard core 당신 are, 당신 can cut Dobby's and Kreacher's heads from posters and stick them onto the 벽 (joking). Black family crest is compulsory.

또는 Ron one... Quidditch oriented. Harry playing, Cannons poster, Viktor Krum poster, Irish Hat, textile Clovers, brooms, Snitch hanged from the ceiling.

또는 Harry Style: totally ordinary bedroom with a calendar on the 벽 counting back the days till the 1st of September and a whiny bird in a cage. :DD

Good luck.

What house are 당신 in!?

Thats a big deal, like Im Slytherin, so I have green walls in my bedroom, with like a silver and green bed-set. I have snake-themed furniture and a slytherin pillow/throw blanket. (You can buy those online for any house.)
I have Harry Potter posters on my walls, and I painted some of my 가장 좋아하는 quotes.
And the Deathly Hallows symbol is also painted there.

Over my bed, I have the Hogwarts crest (its like a REALLY big sticker I bought online)

Thats what I did. But 당신 could do something similar, with your own personal favorites. (If ur not a slytherin, change the colors, my posters are Severus, Draco, Bellatrix etc, so if those arent your favorites, change them!

당신 could do something like this i wouldent overdo it too much
