How to Easily Create Texture in Acrylic Paintings.
Being a jeweler I am always thinking of textures to add to my paintings for more of a 3-D effect and interest. All you need is a lot of Gesso or an acid free "glue" like Collage Pouge found at craft stores in the decoupage section to glue various things like bubble wrap, string, hole punch paper, plastic bags, fabric, etc.
First, you want to glue your texture with the Collage Pouge or other acid free glue; some people just use Gesso for this step but glue is much easier for string because you can just dunk the string in the glue.
Another way (a cheaper alternative to stuff you buy in the art store) to add texture is to mix some Collage Pouge into some spackle until it is the consistency of frosting, then you can create an endless amount of textures with your hands, fork, stamps etc. Let this dry then add at least a couple coats of Gesso; letting it dry between coats.
Then you can add color! I chose a medium tone for this. After this is dry, I did a wash of a darker blue and dabbed off the excess color to give more depth. After this was dry, I used my finger to highlight areas with a lighter shade and then last, I used a silver metallic powder for even more highlights.
