Hanging a picture frame on the wall? Driving in a nail is simple, but if you're not the handiest person, you might worry about smashing your fingers with the hammer.
Fortunately, there's a reliable trick I've used in countless home projects that works every time. All you need is an ordinary comb.

1. Press the comb firmly against the wall (or wherever you're placing the nail).
2. Position the nail between two teeth of the comb.
3. Grip the comb by its handle.
4. Hammer the nail straight in.
Perfect! You've nailed it without a single finger mishap. The nail is straight, your hand is safe, and the job's done flawlessly. This pro tip from experienced DIYers makes it foolproof.
