various colored cardstock
graphite transfer paper
image you want to transfer
First, find an image you want to make into a card. For my example I'll use a lion.
Color in dark areas with black Sharpie
Choose a few colors of cardstock you would like to use for the cards. It is better to keep it to a few colors. Make sure you have a black (or dark color) and a white and a neutral for the back. For the lion I used a dark greyish brown for the accents, a grey for the background, two shades of a yellow orange for the lion and his mane and finally a white for the snout.
Using the graphite transfer paper to transfer the image to the different colors of paper. Blocking out the colors and choosing a neutral color as the base color.
Cut out the cardstock with an X-acto knife. Be patient and trace the lines that you have made carefully. It is usually better to start with the large blocks of color first. I cut out the lions mane, then blocking out the face and white muzzle. After layering those and gluing together I cut out the dark brown gluing the pieces on as I went in order not to loose any of the small bits. Make sure when you cut to leave some or a lot of overlap to allow the paper to stick and create a 3D kind of layering. Also remember to cut on the cutting board and use a good glue stick to keep pieces in place.
Trim the image to desired size. It helps to use a metal ruler and the X-acto knife to cut straight edges. If you want to make a card make sure to cut it appropriately and score the middle using a ruler so it folds clean and straight.
