step two: switch to a tab and move somewhere (preferabbly in a straight line, so use a square image for reference)

step three: switch back to flipanim tab, you now have a perfectly straight line

step five: switch back to the square tab, move the mouse again, but if you went left/right first, go up/down, and vice versa

step 6: switch back to flipanim tab, you now have a perfect curve

step seven: repeat for more curvez

step two: switch back and forth between the image and the canvas, placing dots (example: if there is a circle on ur image, place dots to make an octogon shape. basically, keep the path of dots simple)

step three: make a new layer, and click and hold on the canvas

step four: switch between the canvas and the image, while moving the mouse in a simple pathway, following the dots. the line should curve on its own, replicating the image
