I started out planning to make a twisted pop-up card with Snoopy dancing across the panels, but it wasn't going to look as good as I hoped so I went for the pop-up book card instead.
C - corner rounder/Corner Chomper
A - alcohol markers. I only have a small selection of Sharpies so it's rare for me to use them for colouring anything.
R - ribbon
E - embossing (SU tin tiles EF)
