DIY - Nail Rack

My nail polish collection is ever growing (not like hardcore dedicated nail addicts who have hundreds of bottles - I still have less than 50 which is enough for me), so I decided to test my DIY skills and make my very own nail rack. I couldn't believe how simple it was, I only needed a hot glue gun and 2 foam boards ! It's not completely finished yet because I need to clean it up and hide all my messyness lol but when I do completely finish it, it will look rather nice ! The hardest part is deciding how to organise it? By colour? By brand?

This photo was just quickly taken when I semi-finished, but at the moment, the top tier is for nail pens (because I'm scared of it collapsing haha seemed very fragile), 5th tier is for topcoats/basecoats/whites and the other 4 tiers are sorted by colour. I surprisingly have 9 shades of pink and yet I really hate the colour pink! I guess that's a lie? I think this rack will motivate me to buy more polishes which is a good thing and a bad thing at the same time - lets not forget I'm a student, in other words, I can't afford to buy tonnes of polishes ever week :'( unless I win the lotto....
