A chipboard "tray" (upside down) sized to fit in the top of the Mini Book Nook (to hold mini lights in place or to hang tiny plants from).
Open at the back so the LED wires can exit the book nook (the insert has walls along 3 sides).
It's a snug fit (it isn't glue into the book nook in the photo above with fairy lights lit). But you'll probably want to glue it in place once you have your elements finalized.
Oh, the second photo above with the insert on the bottom is upside down.
Laser cut from mid-weight chipboard; may not be white as the color shown in the photos.220501new GND 220630SC
