The spinning rack cost about $17 to make, plus a few scraps we had at home. This one on Amazon is smaller, and it costs $57 - yikes.
Cut the pegboard into 4 pieces that are equal and fit the four sides of the square board. Then use wood glue and screws to attach the boards to the bottom board. Trevor attached 2 sides then put up the skeleton of a 1x2 in the corners to add more stability, then attached the other 2 sides to the base and corner boards:
Paint it if you'd like. Here's the view looking down into it:
And the outside. The lid just sits on top of those corner boards. And there's a knob on the top so it lifts off. I love that feature and store lots of headbands inside when transporting my display:
And here it is loaded and ready with the fun $1 Starlet Shimmer things - now the little girls can spin and browse to their hearts content - wahoo!!
If you need a spinning display rack for any reason, give this a try!
