Lately I’ve been playing with combining heavier body acrylics with fluid acrylics. This can be done in any order. You can have a wet layer of fluid acrylics on the canvas, and then use a brush or better yet a palette knife to smear thicker acrylics into this. Or, you can have the thicker paint down first, and then pour the fluid acrylics on top and spray them to get them moving. These methods make colours and textures that are great fun to work with.
