I posted about this over on my journal, and I thought others might be interested.
It's a style of art presented by Alison Kolesar, which she calls "Pattern Ladies". They're fun to do, although a bit fiddly. You can get an initial month of Skillshare free, but after that you have to pay a bit every month. Basically, these are portraits of women against a patterned background, and their top or dress is done as a simple pattern as well. I like the retro look of them. Alison does them with watercolour for the figure and gouache for the background and often their clothing, but she suggested any combo of media, like markers or coloured pencils, etc. the different media are to separate the figure from the backgroumd a bit. There's a link to the class at my journal post.
