The Creative glitter powders are the Metro powders, also glimmer and twilight.
The consistency with glitter is a bit different to regular powder so your mix ratio will need to be adjusted to compensate for this. You might want to get comfortable with the mix ratio using your regular powders first before trying the glitter. Once you have mastered the correct mix ratio with regular powders, I think it's then easier to be able to adjust with glitter etc as you know more what you're looking for (hope that makes sense!).
