Fort he longest time my bed and bedroom just had 'useful stuff'. It functioned but there was no particular style to it aside from anime posts I'd gotten in like 2004 and a few additional posters since. About 18 months ago I saw hot pink bed sheets at Wal-Mart and said 'Hmm... :3' Got some Hello Kitty pillow cases next. Around Christmas I found a pink/black comforter to go on top. The last bit was to replace my blankie; A a twin size Disney comforter that I had used for 25 years on the couch and on my bed. The print had entirely faded off, the stitching that kept the stuffing in place vanished, fresh out of the dryer it was more like a thin sack of old cotton that needed to be shifted around to be a blanket again. This week I got a hello kitty twin comforter to replace it and that's done.
The décor in my bedroom needs to be updated next, there's a lamp I have my eye on but I'll wait till September for that but I thought I'd share.
To sum it up, I finally have the bedroom that I should have had since I was 12.
