There's nothing like some soft pillows or cushions to sit on when you invite a bunch of friends over for a video night. Measure a square around the design and cut that out. Sew the right sides of the two squares together and leave an opening along one edge. Stuff it full of batting and handstitch the hole up. Themes Choose a theme for your room and then hit a dollar store and thrift shops to find items that fit your theme.
Some examples are nautical, sports, tropical, etc.
For the tropical you could buy a bunch of bamboo mats and hang them from your ceiling, an inch from the wall. Tack some to the ceiling and start collecting tropical stuff. You could have a few shells along the windowsill, some Hawaiian postcards up on the bulletin board. Let your imagination go wild. Curtains Curtains add a lot to a room.
