These aren’t just woodworking related there are also some home DIY hacks in the video.
Other hacks I like:
When I need a small wedge I take a clothespin apart, then I have 2 small wedges.
To stop tiles from breaking when drilling in them put some painters tape on the spot your drilling on.
Using a rope DIY clamp instead of more expensive clamps. There are many places where you can learn to do these. However the basics of it is you tie the rope around the project, then you use wedges to tighten the rope. This is frequently used with chair legs, because the legs are too long for traditional clamps.
