This is the second background technique in Trish's 2008 Background Noise Sketchbook Challenge. In making my journal page I cut off 2" squares of the backgrounds I made. I still have a good sized portion of each background to use for ATCs, tags & other uses.
I was too impatient to wait overnight for them to dry. After 5 hours, I ran Color Box Chalk inks over the glued surface, they were just a little tacky. My red fingers added extra color to the last blue card I colored.
