one time i put snowflakes i made out of paper and put them on string then hung then room the ceiling (but if youre going to do this be careful not to fall) or you could put Christmas light all around your room or add a small or average size Christmas tree somewhere. i bought a fake small one about a foot tall and decorated it and it looked beautiful! have fun and Merry Christmas and Happy Holidays! :)
Put up a small prelit decorated tree, put Christmas sheets and pillow cases on your bed. Put a throw over your chair, next put a smiley snowman face on your bedroom door. Last, but most important place your bible, opened to the Birth of Jesus, on your dresser, Luke 2: 1-20. Now, Have yourself a Very Merry Christmas ???
