As well as Zentangle I have also got into Art Journaling and while blog hopping (as you do) I found a fun challenge. It's called Index Card a Day and can be found HERE.
The idea is that you use index cards to create a mini piece of art every day for 61 days. Tammy who hosts the challenge gives prompts each week as suggestions for you to follow. This is my first time trying this and it looks like it will be a lot of fun.
Here is my first attempt using the prompt "zebra"
I painted zebra stripes in acrylic on my card and then glued on a Zebra silhouette.
