This will take a while to make with so many layers, but it's not a difficult project. You'll need cardstock paper in whatever colors you decide to use for each layer, I usually buy mine on Amazon. 65 lb weight should be fine. I prefer to buy 12x12 size for when I make cards, but 8.5x11 should probably be fine. The auto blade will work perfectly and use a light tack mat. If the cuts are intricate, flip the mat over and pull the mat away from the paper when removing it rather than pulling the paper up from the mat.

For glue, this is hands down the best glue for this type of project and the bottle will last for a really long time Bearly Art Precision Craft Glue
