I've been interested in pressing my own makeup since the summer, but didn't try it until early November, when I made the first palette. I made the second palette a month later.
One of the things that put me off originally was the high cost - a 15-well palette with tins is about 8 bucks at Coastal Scents, and I wanted to press more than that.
So, I decided to improvise. I bought two 12-shadow palettes at the dollar store, scooped out the product, cleaned them with rubbing alcohol and cotton swabs, and had palettes for cheap! Since I was pressing directly into the palette, they didn't turn out as pretty as they might have had I had the pans out of the palette.
I used Fyrinnae's Powder Modifier and rubbing alcohol for this project. Each tin holds half a 5g jar worth of product - I mixed directly in the jar with a toothpick, or the little plastic scoops from TKB trading. Each jar took about 8 drops of Powder Modifier and 10+ of alcohol. I find it easier to make a soupy mess the consistency of Oobleck than to press crumbles. I pour the eyeshadow Oobleck into the tin, smooth out, come back a couple hours later, press with a piece of cardboard cut to the size of the tin and wrapped in plastic wrap, then press with a cotton pad to absorb some of the extra alcohol and leave the pattern. No pics of the process, my hands were all dirty! You might want to wear gloves.
Note: this works well for shimmer and pearl shadows, not so hot for mattes.
Also note: I pressed some micas from TKB trading into a sample jar (green and blue jar in one of the pics from my collection post), and got a crumbly semi-solid mess. Pressing a Pure Luxe shadow gave me similar results. Pressing a bit and seeing how it acts is a good way to find out if your product is a finished shadow or straight mica.
Here's the palette as purchased from the store - I would never wear this stuff, it was too stinky! (I hate synthetic fragrance in my makeup)
Here's the first palette I did - names of colors written on plastic cover sheet.
Here are the swatches, over ELF mineral primer:
