I actually completed this project a while ago, but I happened to have some photo documentation so I decided to make a post~
There are tons of tutorial posts like this one, so why bother writing one myself? Because its my turn to show off ┌(; ̄◇ ̄)┘
I have a pretty hefty stash of decoden supplies to begin with, but I'll include some places where one may be able to establish their own stash ^^ I'll only suggest links that I've actually used.
There are many many things available here, and one of the shops greatest virtues is that shipping is reasonably fast and inexpensive. The supplies are very good value, and it is very easy to find exactly what you are looking for. Their stock includes nail sets, nail art supplies, and decoden supplies.
However...if you're in a hurry to get your supplies, this is NOT the place to go. Although shipping is free, it's pretty slow. This shop sells many types of beauty supplies, rather than specializing in items for nail art. Most items are sold in sets inexpensively.
I like to keep my most popular supplies in a little plastic box to keep things organized, like this:
As for the glue that I use, I find E6000 to be the most cooperative.
And now for my camera transformation~
The last few pictures are less-than-desirable in quality because my camera was not in a position to take photos of itself at the time, and so I made due with my phone >_>
Anyway, I hope that someone can find this post at least a bit interesting or helpful ^^
