The photo shows the tools I use pretty much every single time I scrap (Not pictured is my paper trimmer, a basic Fiskars portable 12" trimmer). My trusty cutting mat, metal ruler and craft knife for cutting photos apart (when I print several on a sheet), and sometimes also for cutting cardstock and patterned paper if my trimmer isn't behaving. My ATG gun which is pretty much the only adhesive I have used for the last five years! And my precision scissors for cutting small images out, either stamped images or motifs from patterned paper.
What basic tools do you turn to every time you scrapbook?
