If you have a cut on the tip of your finger, don't despair when your bathroom first aid box only contains regular, straight plasters instead of those specialised fingertip bandages. You can make one with just two snips of your scissors.

When I get bored at the chemist, I buy gimmicky stuff I don't need. That's how I finally discovered liquid bandage, which it turns out I do need, because it's great for small cuts, blisters, and any cut on my hand. Liquid bandage replaces a normal bandage with a layer of clear liquid applied directly to the wound.
