I used 1 x 10's because I used a photo box to go under the bottom for accessories. I allowed a couple of inches more than the height of the box. I made it tall enough so that the doll could stand in it also, if she is not napping in the bed I already built!
I have a Kreg Jig and used it to connect all of my shelves and the top. Then I filled the holes and sanded them smooth
I took a couple of scraps of wood and drilled a hole in them the size of my dowel rod. I think it was 1/2 inch. I have delivered this and can't find the exact measurements. (I did write them down) I will add them later if I come across them.
I added some molding around the front.
I had a scrap of bead board so I used that for the back. Hard board or Luann would be just as good.
And there you go. Not a difficult project at all. And here it is after I made some doll clothes to go in it. My granddaughter was very excited when she saw it!
