reversible skirt I made for my daughter out of two dinner napkins the other day. Today I'll show you how to make a Crayon Portfolio or Crayon Roll out of 1/2 of a dinner napkin. It's very easy and really takes about 15-20 minutes tops. These are perfect for those little wiggle worms sitting next to you in church or while waiting in a doctor's office, a long car ride, etc. What are you waiting for? This dinner napkin cost me $1. I used half of it, so this project cost me .50 cents.
