Here's the lamp before...
I took the existing fabric off of the lampshade and measured out strips of tulle...double the height of the shade plus some overhang at the bottom, and extra length for the knots too. My strips were 31.5" long.
There are 2 strips of tulle for each knot. They're either 2 pink strips, 1 pink 1 white, or 2 white strips.
Here's how to knot them:
At the bottom, bring the ends down over the wire to the back and then around to the front, creating a loop.
...and tighten. Cut the ends to the desired length.
And I added a big beautiful silk flower (from Michael's) to finish it off. It goes perfectly in the princess room.
Thanks for looking!
*Disclaimer: Be sure that the tulle is taut and rests far enough away from the heat of your lamp's bulb. If the bulb sits too close to the shade an alternative option would be to leave the lampshade intact, create holes in the top and bottom of the shade, and weave the tulle through the holes. I have never had any issues with my tutu lampshade but will not be responsible for any issues a user experiences.
