To avoid staining the embossing, I brushed the ink on the card panel before embossing. By inking the card first does mean you have to wait for the card to completely dry, and use an embossing buddy before you attempt to heat emboss, or you'll find the embossing powder sticks to the whole area rather than the design. I certainly think the inking adds a little richness to these cards. I hope you agree.
Time to try more colours and techniques with this stamp.
