To get a good look you need to use a good quality- the metallic craft paints won't give you the depth and quality you are looking for when creating artwork that you want to stand up to the test of time.
My favorite brand is Jacquard Lumiere Metallic Acrylic Paints. They come is a wide
range of color selections to choose from. They are not extremely pricey and have a great quality.
I like to go to Blicks and select what I want, but for a full range of colors, it is best to go online. I have purchased from Amazon, but there are many options out there.
Here are some of the pieces I have created using these paints to give you an idea of what can be done.
This necklace used a combo of gold and copper metallic paints. See more details
Blue and gold metallic paint was used to make this necklace.
This altered paint brush was made using metallic green, russet and copper paint.
This mini altered birdhouse used red metallic and copper paint.
This is a mixed media canvas piece that used my full range of paints to highlight the objects !
So as you can see- these paints can really add to the interest of your artwork- you should give it a try.
