I drew each of these cards over the course of a couple nights. I used melted crayon for the dots, china marker for the dark bold colored lines, and pencil / pen for the interstitial lines.
Something that I find really cool is the fact that I listened to the song Anklebiters on repeat while I was making these, and at the time I had NOT seen the music video, but after watching it when embedding it in this post I see a TON of weird artistic similarities between the music video and these cards.
Here is the song Anklebiters by Paramore as well as some of the individual pieces of inspiration I found myself thinking of and looking at while doing this piece.
Anklebiters by Paramore
Fun with filters
Using the toolbar on the page you can invert the colors and it makes the piece look really cool too!
