G.T. Luscombe sells my favorite Bible marking tools. They sell to stores instead of direct to the consumer but most Bible bookstores, including Christian Book, carry their products. They only distribute Bible safe marking tools.
Jann Gray sells some of the GT Luscombe line of journaling products on her website, Illuminated Journaling. She also offers journaling classes both in-person and online and is the author of a couple of my wife’s favorite books about Bible journaling. She just started an online class about watercolor stamping.
