If it is a pressed powder;
obtain this
I have found little containers like this at a dollarstore in the travel supply isle or even cosmetic isle.
Then, either drop the eyeshadow you wish to mix
(so they break into a crumble) or simply use a small tool to break up the fine powder.
Once your eyeshadows are a loose powder, add the desired amount into this small container and mix well.
Lastly, press the loose powerder back into a compact.
(I have had to press my eyeshadow back into a compact after accidently dropping it)
P.S I have never mixed eyeshadows before..
How do I remove a cake from the bottom of a pan?
