Papertrey Ink has a new how to video and challenge every Monday. This week we were to stamp white pigment ink on white cardstock and then stamp with dye inks to see the ghost image of the white pigment come thru. My example is very subtle. I used a Hero Arts stamp – Leafy Vine as the background and stamped it with unicorn white pigment ink. For the dye stamping I used various Hero Art inks and PI stamps – Flower Fusion #7, Delightful Dahlia Additions , Funky Florals, and Harvest Berries.
