In a children's room, it just makes sense to store books facing flat. Then children can put their own books away. Also, flat bookshelves take up less floor space, a bonus for often tiny secondary bedrooms. Special thanks to Matt, Heather and many other readers for sharing their photos.
1 – 12′ 1×6 Board (cut sides out of this board)
2 – 1×6 @ 57″ (Sides, Top Cut out in step 1)
Side Cutouts. Using the measurements above to guide you, cut out the sides at the top as shown above. Once one side is cutout to your satisfaction, use it as a pattern for the other side. This will keep the side the same. Use either a bandsaw or a jigsaw.
Box. Build the box by using 2″ screws and fastening the shelves to the sides, as shown above. Measurements above are to the bottoms of the shelves.
Back Supports. Fasten the back supports to the sides and the shelves. Make sure the bookrack is square before this step. Use 2″ screws and glue.
Front Rails. Cut out 4 of the front rails (1×2 @ 22 1/2″) in a simple arch shape above as shown in red. Then, as you did the back supports, fasten the front rails in place. Make sure you bookrack is square before fastening the rails, as this step will set the bookrack.
Finishing. Fill any holes with wood filler and sand and finish as desired. Screw through the back supports into a stud in the wall to keep the bookrack in place. You could alternatively use a picture hanging kit to fasten the bookrack to the wall.
