If you're using drywall screws, you'll want to countersink the holes. Drywall screws are flat-head, and need a countersink to seat solidly. If you're using Kreg pocket screws, the way I did, you won't want to counter-sink the holes. Kreg screws are pan-head, and seat just fine against a flat surface. Both drywall screws and Kreg pocket screws are self-threading, so you don't need pilot holes in the second sheet of MDF.
Some tools required for this project are hole saw, drilling machine, pencil, tape measure, clamps, etc. This tutorial explains every step properly with images so that anyone can make a wooden sofa sleeve easily. Those, who prefer a video tutorial, can visit the below link to a YouTube video that illustrates the process of building a DIY Sofa Sleeve Cupholder.
From the image above it seems that you do not require a big tutorial to help you to build this candle holder. All you need is a wood panel, a hook and some nails/screws and do exactly what you see in the picture. Attach the hook to the wood panel using two screws and then, attach the panel to the wall using more nails or screws. That’s it. I hope this gets the job done.

If the holes of the first jaw are in the proper position, drill holes in the same locations on the other jaw. I lined the drilled jaw on top of the undrilled jaw, clamped things down, and then drilled about 1/4" into the undrilled jaw, to mark the location. Then I removed the drilled jaw and drilled out the marked locations the same way I did the first.
Our stationary equipment runs the complete range from heavy-duty industrial machines, to inexpensive home shop type of tooling so that each student can compare and contrast the range and versatility of equipment at a wide variety of price points.  We spend time on what makes a good machine good, an adequate one adequate, and a lousy machine worthless. We have no commercial sponsors and will share our opinions based on our experiences regarding the quality of one manufacturer over another.  There is no better place to kick the tires on a variety of equipment than at our shop.     
The book is well written and easy to read. The illustrations, I'm sure were excellent in 1914 and, are still adequite now. Most of the designs seemed repetitive, though. I wish more attention had been given to lashing materials. If you are looking for that you will find almost none here. The book was fun to read and provided enough inspiration to make my brother and me attempt a large hut.
