This is a very simple thing to do and all you will need is a roll of tape (in my case I used a small roll of thin masking tape), a pair of scissors, your nail polish bottles and some patience as this may prove to be time consuming depending on the number of polishes you own. In my case I was sitting there for about an hour and a half but I was also watching the TV so I was just taking my time.
All you need to do is:
- Use your scissors to cut the roll of masking tape into small squares. I found it good to get a lot of these cut out at a time and then lined then up along the edge of my desk, ready to be used for the lids.
- Take one of the small squares and paint a swatch of your chosen polish in the middle of the tape. I'd recommend making sure the swatch is opaque as it will make identifying the color a lot easier when it is dried.
- Stick your painted piece of tape in the center of the nail polish lid and use your nail to secure the edges of the tape.
