As for what lipsticks are suitable as bases, I'd say anything would do. I like MAC lipsticks for this purpose because of the pigment in them and the texture. I wouldn't use an expensive lipstick such as Chanel just because...well, they're expensive! Dustyohunter on YouTube has a lovely informative video on depotting lipsticks, which you an view here. Instead if leaving it in a solid state, I put it in the microwave and heat it until it starts melting. When you melt a product, it changes the state slightly so it becomes creamier and easier to apply. In the picture below, I have several pots that are of mixed colors which adds a little more depth.

I use my fingers to apply onto the apples of my cheek, then layer a blush on top. The combination makes for a very long wearing cheek color. Depending on the formula, bases also add a nice sheen to the skin, which eliminates the need for a highlighter. A Frost finish will give a nice shimmer, while a Lustre finish will be more dewy. If you have a very, very light pale shade you could melt it and use it as a cream highlighter. This is a fun project to do if you are looking to de-clutter your stash or even if you're bored =D. Have fun and experiment! I consider myself pretty artsy (I fail at math but I excel in art =_=') so I was having too much fun mixing things. Just don't hurt yourself in the process. What projects do you like doing?
