Start with a bandaid (any brand will do) and a pair of scissors.
Unwrap bandaid but DONT take off the white paper on the sticky part. In other words, don't expose the adhesive yet.
Take your scissors and cut the sticky part in half but only up to the pad on each side.
This is what it will look like on the other side. Notice it is only cut up to the pad.
Remove the white paper to expose the adhesive. Wrap the bottom strips of the bandaid around your finger first.
Bottom strips done.
Then wrap the top strips but fold down to make it fit your finger.
Cross one over the other. This makes it fit your finger without gaping!
Happy finger, no gaping bandaid!
