I got my Micas from www.tkbtrading.com.
They are called Pop! Micas. I have made my own eyeshadows for a long time but i have never thought of making a tutorial for it until i saw another girl's homemade mineral eyeshadows :)
I'll put up some "recipes" later. :3
Before you do anything , disinfect every thing you are working with. I use 70% rubbing alchohol.
Also, you should put on gloves and a dust mask.
Here is what i used.
I got the Micas from TKB Trading and i got the baggies and stackable jars from Michaels.
Then decide what color you would like to make.
I'm am going to make a light purple color.
Start by picking out the main hue (purple) then add a scoop of that in your baggie.
If your color has two tones
ex: blue green
add the second hue
If you want to deepen the color, add a a scoop of it's complimentary color.
(The color across from it on the color wheel)
If you need to lighten or deepen the color, add a scoop of either black or white.
Then mix it all up !
To add more depth, keep adding colors until you are happy with the results.
I like to keep what i've made organized by numbering them then putting the color on a piece of tape.
Then i tape it into my sketch book along with the "recipe" so if i run out of the color, i can make it again.
If you want, you can snip off the corner of the baggie and transfer the eyeshadow into a 5 gram jar.
