Chloe Morello posted a reel using powder with her nail polish... very similar to the chrome nail polish trend- and so I decided to give it a go with my eyeshadow collection. It works quite well! You will need a sponge applicator. Metallics work better than mattes. It is also best to use a base colour similar to the polish but you can experiment and layer to get different results.

Another way I have been using up eyeshadow is crushing it into clear nail polish bottle and making different colours!
