One of the most interesting acrylic pouring techniques is hands down Rinske Douna's Dutch Pour. Known for its flowing floral and natural shapes, and the use of a blow-dryer to move paint around.
The problem for a lot of people is that blow-dryers have different power outputs and nozzles, and they're not necessarily a purchase you want to make to try a technique. In addition, the use of a blow-dryer, which usually has a wide pattern, creates a minimum size of canvas that you can use and therefore a minimum amount of paint. Long story short, this can be a costly learning endeavor.
So what if, instead, you could work on smaller canvases using less paint? And instead of a blow-dryer, we just use a straw?
The materials you need are simple:
Acrylic paint - I'm using this Liquitex Basics set
Floetrol - but another pouring medium could work.
A stick and a straw!
Three parts of US Floetrol to One part of paint. If you use a pouring medium that's thicker than Floetrol, add a little bit of water.
You first apply your background color.
Make sure to completely cover the canvas.
Then you apply your colors on top of each other in a line.
Make sure to leave enough space to actually blow out the colors.
Surround the colors with more of the background color.
Blow the background color over the colors from both sides.
Begin blowing out your petals.
As you blow out a petal, notice how right next to it, a pool of excess paint is created.
Aim for the pool on your next blowout.
Repeat until satisfied.
Use a stick to create arcs from the background into the petals. Always start outside and go inwards.
