It's super fun to use loose glitter on your nails. Simply because they are much cheaper than regular polish; I got mine from a local craft store for only 99 cents. For this mani, I hand placed them randomly on my nails. I use small dotting tool to pick up the glitter and place it on my nails and sandwich it with a natural coloured jelly polish.
Well, in terms of application, definitely regular glitter polish is easier to work with but yeah I just love trying something new. If you guys want try do a DIY glitter polish by mixing glitter and clear polish, you can, but personally I don't really recommend doing that.
Once I tried to make gold flake topcoat polish with clear polish and gold sheets I bought at a craft store. First they look fine. After an hour the gold flakes sort of sinks into the bottom and is super difficult to catch. After a few hours I have no idea why the polish turned green. It's helpless so I ended up throwing the whole thing away. So now if I want to have that gold flake effect, I have to hand place it just like I did with this one.
