Maybe you should try using konad paint, which is specially formulated for stamping while you're starting out.
Vinylux wouldn't be the easiest stamping polish in fairness.
Also, you are being advised to be super quick with your application, but maybe you're doing it all a bit too fast?
Grab a sheet of paper to practice on, so you're not constantly wiping your nails.
brush on the polish, scrape once, (I find using an old credit card the best), using firm, but not too hard pressure, press down on the image.
Have a good look at the image to be sure it's all picked up and edges are sharp.
When you're happy, roll the image onto the sheet/nail. It should all take about 30-40 seconds, that's q
uite a long time. So don't rush it!!
Take your time, it'll come to you and it'll be a light bulb moment when it happens. The satisfaction is worth it!! Lol
Good luck
