These turned out so pretty...I wish you could see the shimmer from the pigment powders IRL...they sparkle and shimmer like you wouldn't believe.
All I did was spread a layer of white glue over the canvas then sprinkle on the powders. I left it to dry and the results are what you see.
I wasn't to show you the amazing texture of the surface of the canvas...it's really cool looking...
The speckles that show up really well in this photo are the bright shimmer of the powders...some areas the color is more prevalent, other places it's the shimmer. Just such a nifty result.
This is another canvas I did but I misted the top of the glue with water before sprinkling on the powders. I also took a tool and made circles in the glue right after I sprinkled the powder on. You can see that (because of the water) the colors traveled more freely but the glue did hold some of the swirly designs.
I think this is going to be a really fun technique to explore more in the future, more ideas rolling around that I want to try.
