6 Paint frame with knotwork

I dilute acrylic colour with a lot of water. I use a similar workflow to watercolour painting; the difference is that acrylic colours are waterproof, so once they dry they cannot be smudged with the upcoming layers. First I paint the whole frame ‘wet on wet’ with ochre colour with variations (a bit greenish, then lighter brown to avoid a generic, flat look). After it is dry, I paint shadows with the brown diluted colour and small sable brush.
