The supplies I go to again and again are:
1. Tombow Glue Stick--It's super thick and will glue down any paper..even if it's super thick, or several layers of paper.
2. Pitt Artist Pens--Love these pens, the neutral colors come in Superfine, Fine, Medium and Brush, and all the colors come in Brush. My favorite are the sepia pens. great for everything.
3.Watercolor cardstock--I use this all the time.
4. Xyron Adhesive Runner--I love the ease of this adhesive.
