I use many note slips from cutting scrap paper into eight pieces. A few years ago I adapted a business card holder to hold these note slips. That card holder is no longer sold in stores. I wanted to see if I could make my own from some 1 1/4 inch electrical conduit PVC I had left from another project.
Step 1: Cut the Paper
My scrap paper is 8 1/2 x 11 inches. In many countries the standard paper size is A4, which is just a little larger and is sized in metric measurements.
This is a paper cutter given to me and my wife by my in-laws many years ago. Although not easy to see in this photo, I painted a red dot on the left side scale at 5 1/2 inches, 4 1/4 inches, and 2 3/4 inches. This marks for easy cutting into halves, quarters, and eighths.
