Wow, not one soul mentioned MAC's new Paint Pots? I'm surprised! I absolutely adore mine. It's called Bare Study, not Bare Canvas, and is a light gold color. They're technically cream eyeshadows, but hold my other powder shadows better than anything. You also get a heck of a lot more product than in a UDPP tube! And it has the benefit of being used as a super quick eyeshadow if you're in a hurry one day. Bare Study is truly amazing and lasts forever. I've used mine practically every day for months and it's still mostly full!!!
*Edit - I realize the poster asked about Bare Canvas, but Bare Study trumps it so much more, I wanted to share. The Paint Pots are *way* less drying than Paints.
