Here's a constructing description as well as some more pictures of the contraption above my bed just for you, Melissa:
Step 1: Saunter into your backyard or a nearby field and and gather up a group of stray branches.
Step 2: Cut many 3 inch wide strips of tissue paper in the color of your choice. Lengths may vary.
Step 4: Twist the strips of tissue paper about every inch and a half.
Step 5: Cut squares of green tissue paper and glue your long (in my case pink) strips of tissue paper to the center of the green squares and twist to form a peak in the center of the green square.
Step 6: With a hot glue gun, glue all of the green peaks to your branches in any desired location.
Step 7: Cut strips of tulle according to the number of branches you have- I recommend white if you have a white ceiling so they won't really show- and tie the strips of tulle to center of the branch so it will balance properly while hanging.
Step 8: Stick a thumb tack through the top of the tulle strip and tack to your ceiling!
I hope this description is clear. Just shoot me with any further questions. Happy d.i.y.ing!
