I am happy to say I got to stop by our local Dollar General and bought three clear on-one-side pencil cases (used in 3-ring binders). A red, green, and blue and nice bright colors. They are perfect because it's lik each has a little window to see the contents. The color part of each bag is that nylon fabric, and it should sew just fine. I paid $1 each, so now I guess it's time to hit my stash.
If I DO find enough time to finish, I will certainly post a picture.
