The number one thing I've been asked over the years regarding bible journaling has been, "What about covering the words?"
For me, I have dedicated bibles, and covering the words sometimes, is not a HUGE issue; however, I do try to not cover them for the most part. I use a lot of watercolors and stick to the margins.
With all this in mind though, I decided to create transparent stickers. They can go right on top of the print and you can still READ the words!
