Grab a sheet of white cardstock and randomly color it with markers. I used my Chartpak Ad Markers, but any markers will work.
Start doodling with a pen color that will show over all the colors. I used a black pen and some tangles from the Tangle Patterns website. Cover the whole sheet of cardstock with the doodles.
Measure and cut the cardstock into 10 rectangles that measure 2.5" by 3.5".
Protect the doodles with Mod Podge or a varnish and add artist information to the back of the ATCs.
Voila. You now have 10 beautiful doodle ATCs to share with friends or strangers.
Do you make ATCs? Do you doodle?
Have you ever made anything like this project?
