I bought the window box from Lowe's for about $12. It was black and had some moss in it and some attachments that I didn't use. I spray-painted it white just because the fabric cover will be white.
I wrapped a double layer of batting around the front, top and sides, using clips and clothespins to keep it in place, and clipping the excess on the curves. There's about an inch overlap on the edges. Once I got a good shape I hot glued the batting to the metal frame.
Turning the scallops right side out, the CD helped to iron them flat.
...pinned, and sewed onto the front of the white satin cover.
The curtain sheers were put on by sewing 4 strips of ribbon to the top of each panel and then I tied them to the metal window box inside. That way I can take them off to wash them. I added the puff ball trim to the curtain shears and tied them to the bedposts with thick pink ribbon.
My oh-so-kind and handy husband helped to hang it up on the wall. Now the princess bed is complete!
Thanks for looking!
