First you take your boards and your long sticks. Take them and screw drive them together as shown in my picture. You need 4 of those long sticks. They need to be strong enough though to hold all the weight. Now when you are screwing them on to the boards make sure you have a little bit at the end of the last board so it can stand on the floor.i also have a picture of that.
Step 2: Finishing Touches
After you have done your frame start putting tiny twigs all over it you just nail it in with tiny tiny nails like the picture I have. I hope you have a fun time reading all those books with that awesome bookshelf to hold it!
