Colouring over glitter

Inspired by Craft Stamper's latest issue I had to give this technique a try:

I've use CT3, OR1 and OR3; CG1 and CG3; EB8 over normal crystal glitter on Jac paper. Pens wiped clean on a scrap of paper towel after use. Colour touched on - no attempt at blending on this surface. The stamps are from StampIt sets 019jh and 014.
