Lately I did some reels over at Instagram (@mixedmediabeagrob) where I showed in timelapse how I do first backgrounds, then add with pencil different types of faces. The next steps are painting with acrylic, adding marks and more detail to the background. The final step is polish up with colored pencils. Those paintings fits the Ikea Ribba Frame perfect, as I show also in the video. They also can easily be sent in an envelope together with some cardboard to prevent bending. Yes they are on my website here right now.
As I said it was a Reels video so the format is different, but I think you get the idea.
