Hang Christmas Lights: They make every room look complete. Use standard outdoor lights and wrap them around the inside trim of each window. You can also use the icicle-type lights and string them underneath your beds as well as the perimeter of the room by hanging them around the edge of the ceiling.
Mistletoe: This can be good potential fun, except, don’t hang it right over your own doorway… unless you plan to kiss all of your visitors.
Paper Snowflakes: The easiest form of decoration. Simply fold a piece of scrap paper three or four times and cut out shapes from the folded paper. Unfold and decorate your snowflake with glitter to add a little extra shine.
Personalized Stockings: Assign one to each of your roommates, add personalized name design and trinkets. Don’t forget to add a gift to each one before break starts as a little thoughtful touch.
Small Artificial Tree: With the limited space, a large tree just won’t do. You can purchase any small artificial tree with pre-assembled electric bulbs, saving you tons of time. Add your own theme of decorations and don’t forget to wrap up small gifts and place them under the tree for your roommate.
