Actually anyone can make a pen roll. I took a bandanna that I really liked and used it for the outside of the roll. Then I found some coordinating flannel, which I already had on hand.
Stitch the two pieces together, design side and soft side in, leaving a small section open. This will allow you to turn the design and soft sides out leaving your stitched portion inside. Stitch the opening closed by hand.
Now you need to fold over the bandanna and stitch your pen pockets.
I hand stitched a ribbon on one edge which allows me to tie the roll closed.
Voila, one pen roll!!
