Square paper (small)
1 piece
Glue/tape
This fits perfecly on my finger as I could push it down.
Get a square paper
Fold a triangle
Fold the ends together
Open it up. It shold leave a line
Fold it on to the line you just made
Fold it again
Fold the tip down halfway
Now fold it up but don't do it all the way
Now fold it in half like so
And tuck the tips together
Then tape it up or glue it. Tape works better
It should now look like this
