This is really a v.simple tutorial. It will take ten mins for making and a day for finishing(depends on the glue you use). Lets see, how to make it. We will need pencil leads(i used 2mm), wooden beads from a bracelet(they are rectangular and have three holes) and glue. Insert pencil leads into the holes and glue them. Let it dry completely. Your rack or shelf is ready to be mounted on wall. Njoy :-)

P.S: Make sure the leads are fitting perfectly into the holes. If they are little less diameter than the hole, then use some m-seal to fill the gap.
