I did my first one yesterday - a replica of "Let's Patch Things Up" in fall colors. I knew it would be a lot different than watercolors, and at first I thought I didn't like it as much, but it turned out okay in the end (I'm never happy until my hand is cramping from adding the pen details anyway)! I need to work on doing backgrounds though... I'm used to leaving it white on watercolors, but I don't like that look on canvas, so that will be a work in progress!
If anyone has any starter advice about Etsy - I'd love to hear it! Just comment or email me!
