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.
And the "150 premium woodworking videos"? Those are all publicly available videos from YouTube and Vimeo.com, embedded in the website. And these aren't even particularly good videos. The newest of them is from Dec 2010. Some of the links are to videos that no longer exist. I guess the list hasn't been updated for some time. At any rate, you can see much better woodworking videos, free of charge, by going straight to YouTube.
