I believe wrapping paper will get yellow after some time and won't look that good anymore after a while, for my dollhouse I mostly used scrapbook paper, the scrap book papers are too small but you can cut and paste them together I will show you some pictures:
^ These are two pieces of scrap book paper put together with borders to make it look like 1 paper.
^ I did the same here as well.
