For this hack you need a spoon, and you pretty much use that spoon as a stencil for the edges of your wing.
You use the handle of the spoon to stencil the bottom of your wing, and then use the spoon part to stencil the line and curve of the wing.
The liquid liner got under the spoon and made an uneven line for the wing, and then the curve on the top wasn’t thick enough so you could barely see it.
For this hack, you cut your own stencil into a stick piece of paper (I just made a small triangle cut) and then just hold it up to your face where you want your wing.
