This is what I've been doing for the last few weeks in my spare time. I've been swatching my polishes onto sticks and labelling them so I can see quickly what I have and what will go with what. It also helped me identify any dupes that I had but didn't realise I had.
Problem was that silly me only ordered 100 sticks and honestly I thought that would be plenty. I severely underestimated how many polishes I have so I have now ordered another 150 sticks and hopefully that will be enough for me to swatch the rest. I just found these on ebay and also got the stainless steel cable wire keyrings from ebay too.
I have them separated into their colour groups on the wire keyrings.
I also found this helpful to match indies/glitters/top coats etc to a base colour.
Thanks for reading
