Introduction: Another Easy Illusion. the Bendy Lines

Another easy illusion on paint.
This illusion shows 2 lines that appear bent but are
actually perfectly straight.

Step 1: Step 1

open paint and make a plus with the smallest line tool.
Continue to add the diagonal lines as well.
try not to go far from the middle join point.

Step 2: Filling In

slowly fill in the space untill looks reasonably good. (do it by eye)

Step 3: Trimming

trimm the edges and add a few more lines if you need to.
lines always able to change to preferences, try a few ways.

Step 4: Finishing

once you have trimmed the edges make two yellow lines of the thickest
kind through the lines a bit above the middle.
i said yellow because thats what i did but you can try different colours.
