From time to time, people ask me about my paint tin.
Currently, I use a Schminke tin that I have retrofitted to fit more colours. It is small, when closed it is about the size of an iPhone. Open, it has a lot of mixing surface.
You can purchase this tin with Schminke paints. Filled it would have been more than I wanted to spend, but I was happy to learn that you can also purchase an empty tin. This was great since I already have paints.
There is a 14-pan clip insert in the tin that lifts out. I used this insert as a template and cut, out of a plastic lid, another insert. To this, I applied strips of poster tack. The half pans stick onto the poster tack very well. I've even dropped my tin once and nothing came unglued! But you can still swap a colour very easily. Using this method, I was able to add an extra 7 half pans to my tin.
Liz Steel has a photo tutorial which shows this perfectly. She was my inspiration for this.
Coincidentally, empty paint pans can be purchased as well and filled with tube paint. Good news since I can no longer find pan paint where I live!
