Acrylic Spring 20015 Classes

Acrylics 101 Dry Brush Blending

Last week we went over how to do brush blending or wet into wet blending, this week we covered dry brush blending. Dry brush is probably the more useful technique when it comes to blending acrylics you will use it all the time so it is important that you practice and understand how to do it.

You want to use your bristle brushes for most of the dry brush techniques though there are some that you can use you sable brushes and not ruin them just remember that the key to dry brush blending or any other dry brush technique is literally a dry brush. Of course you will have to rinse your brush occasionally but when you do make sure that you have your paper towels handy and you dry your brush completely, you don't want any excess moisture in your brush.

The next thing you need to remember is not to have a lot of paint on your brush. When you load your brush with paint you want to lightly wipe off the excess from the outside of the brush so that when you go to paint you will not have big gobs of paint coming off your brush.

In the last thing you need to remember is the pressure you apply to your brush when you're doing your dry brush. If you press hard you will get more paint out of your brush if you have very little pressure on your brush very little paint will come off your brush and this is important, you want to be able to go from an almost solid color to a color that barely covers the canvas underneath, if you are doing this correctly you will see the canvas or the color underneath the new color you put on (look close you should see the pattern of the canvas created with the dry brush). Because acrylics dry so quickly knowing how to blend colors with a dry brush is very important and can be used in many different ways and techniques.


To practice your drybrush blending rinse you (bristle) brush and dry as completely as you can. Load paint onto your brush then lightly wipe the outside for excess paint. On your canvas start by pressing hard (I was using the narrow side of my brush) and try to go from a solid color to a vague color just by decreasing the pressure you apply to the brush. You should be able to see the canvas underneath when you get to the lightest pressure. Remember that the brush is a tool and it can rotate in your hand like a baton. My brush is constantly moving from the narrow side to the wide flat side to the tip and back again depending on what look I am trying to get or the spaces I am trying to get into.

If you are lightening your pressure and you are still getting too much color or it looks very transparent and/or runny you may still have too much water in your brush. The paint should look very scratchy if you are applying it with the correct amount of water in your brush. Dry your brush again and try it again you have to learn just how much water you can use in the different situations.




Once you feel you understand how to do the dry brush there are several things that you can practice one is to shade the ball like we did last week starting with the dark on the underside and then light pressure until you get to the top where it should be light then you can try other techniques dry brush can be used for wood grain it can be used to create hair and fur it can create a waterfall it can create bushes and grass it can create fog and mist and dust it is a very useful technique to learn.

I ended the class by demonstrating how I could under paint with the wet into wet technique, I let it dry and then with the dry brush technique I created old wood. This is a fun thing to do and when you have success at doing it you will know that you can do anything! Keep painting and I will see you in class.



Acrylic Garden Fantasy Week 3

This week I wanted to get as much of my background bushes and trees in before I painted my pagoda.

Have your reference photos of the pagoda and the stream from the Botanic Garden in front of you when you are painting, this this will give you all the visual information you will need if you just look to see where the different plants have their light and shadow, also, you want to get as much dark behind the pagoda area as you can so that when we put the pagoda in it will look very outstanding against the dark background. There will be a few light areas behind the pagoda around the middle of the pagoda and dark areas around the top and the bottom if you get carried away one way or the other we can correct it once you get the pagoda sketched in. You can always make corrections.

I under painted my trees and my ground cover using my hooker’s green, a touch of blue and purple - sometimes it was more to the blue side and other times it was more to the green side - vary your colors it will make your painting more interesting. I also used gesso (white) or yellow to change the value (light or dark) of my color. I was working wet into wet and by adding lighter colors towards the top of a bush or tree and darker colors to the bottom this starts the shading process.

When you are painting the ground cover be sure that you get the ground cover in and around the rocks some of the ground cover almost completely covers the rocks near the stream this will make your stream look more natural and soften the edges of your rocks so don't be afraid to go over some of your rocks to bring this ground cover over it or behind it or in front of it this is why we put the rocks in first.

I also repeated a color that I had in the background which was an orange red. It's not in the photographs, however, because I put it in before, I wanted to repeat the color so it is not a unique color and I will probably add it again someplace else in my painting.

I did sketch in the pagoda and the trunk of the pine tree but I did not paint them in yet, I want to see if there is any more background I can put in before under painting them.

Try to get your painting up to the same place as I have mine so that we can continue to work on this and finish it within the next couple weeks we are getting down to the final stages and we will be starting on details soon, also, have an extra canvas something you can practice on because we will be doing some work with our liner brushes and most of you need practice before working on your painting. Keep painting and I will see you in class.
