I have a bazillion old Rol-a-dex cards that I thought would be fun to alter. I began trying out my discovery in different colors and couldn't stop!
This is what I learned: stamping on chalk.
I love to work with artist's chalk, but for some reason have never stamped directly onto it. When I attempted it on chalked background on an altered book page, the stamped image was practically invisible. So I touched it--rubbed my finger across the still damp ink. The chalk was absorbed into the ink and the image popped out in the most brilliant color, a darker version of the chalked background! ( A light ink color allows the chalk color to be it brightest.) That is when I started making these little Rol-a-dex cards and could not stop. These are unfinished pieces really, but illustrate the technique.
This is definitely something new to me that I will be using again and again.
More 'new' things can be seen here.
