Did you know that you do not have to limit yourself to only ironing-on JOY letters to fabric? You can put your name or initials on everything you own - if the surface won't take the heat of an iron, just use a bit a glue. I used a letter "R" to monogram my cell phone case, and I added my name to my new day planner for 2016 and I initialed the cover of my journal.
Look for Joy letters and numbers at your favorite craft store - happy crafting!
