On NGS group we are studying Julia Andrus' book "Paper Transformed", this week: "Frosted Embossing". Julia says that because embossing powders (ep) are low-melt resins, Perfect Pearls, which have a built in resin, are attracted to the eps and will bond to most warm eps.
I stamped an image on dark paper with embossing ink and covered with detailed clear ep.
Heated the ep, while it was still warm, brushed on Perfect Pearls. This didn't look much different than ep over VersaMark ink to me.
