Caliart markers are great for beginners, and are double sided!
To blend markers, find similar colors and create a base with the lightest one. (#1)
Take the medium color(#2) and create a layer over the lightest one(#1) wherever you please.
Then, go back with color #1, blending in the sides, and creating a light layer over #2.
Then, go in with your darkest color (#3)blend it in with #2, and blend #2 in with #1.
Again! Blending in #1 and #2.
Blending in the darkest color, and working backwards from dark to light to blend it all together.
Written version of blending caliart markers!
Note: Get thick paper. I used mixed media paper. You can layer more without damaging the paper.
