I don't know if there is a right way to emboss metal, but this is the way that I emboss metal. And let me tell you, it's SOOO easy, and you probably have most everything you need for it already, including the metal. The picture inside of the frame is all embossed metal--

I've shown metal embossing before, but it's been a while, so I decided to show you with a little more detail on how I go about doing it. I use the aluminum
metal foil (36 gauge) that I get at
Dick Blick, but you can also use the aluminun pie tins or any aluminum tray that you can get at the grocery store. You can just wash the ones that you bought that had food in them--they're just as good. And I've purchased a few embossing tools, but the one I always go back to is either the other end of a paint brush or a dull sharpened pencil. The metal usually rips for me when I use a stylus. The foil is pretty durable, but you do have to be careful, and it can be cut with regular household scissors. After I sketch my design lightly with a pencil, I start embossing (you can emboss on either side)--

I knew that I wanted a rooster, heart, and sun on this, so I sketched it on. After that I just doodled with my paint brush tip or whatever my choice of embossing tool that I'm using at the time. You don't even have to sketch anything on--you can make a zentangle--or just emboss whatever comes to mind.
After that, I always put some alcohol inks on it first and when the inks are dry, I apply a black craft acrylic paint quickly, and then wipe if back off again. Just don't wipe too hard, because you'll get right back down to the metal.
Then when that's all dry, I just paint in my design with acrylics, but I recommend the artist's acrylics, because they're much more vibrant. The craft paints are too thin and it's hard to cover the metal. So when all of the paint is dry, I always spray a couple of coats of a workable fixative on it--the paint will come off if you don't. And then when the fixative is dry, I put a gloss varnish on it, so it has a nice shiny look to it.
It's very hard to get a good photo of the finished piece--it's much better in real life. So the frame--well a couple of months ago, I went to the wholesale show in Columbus, Ohio, and I showed everyone these barnwood frames that I purchased there--
These frames had glass inserts in them. So I kept the glass in it, and just adhered the metal piece with extra heavy gel medium right on the glass--it always works! And I hadn't cut the metal just right to fit inside the frame, so I camouflaged the side with textured wallpaper--
I hope I covered everything, but if you have any questions--just ask. So next time you bring one of those trays home from the grocery store, don't throw it out--try this--it's fun.
And here's some more rooster love--
FUN!
I also wanted to show you what I treated myself too. When I saw these earrings on Sharon's blog
I knew that I had to have them--these are me, and I just got them yesterday (very quick service!) I love them Sharon--these particular earrings were published in the magazine Bead Trends, but this isn't the first time that she's been published. Go check out her blog--she's also a very talented mixed media artist.
I hope that everyone has a great holiday weekend here in the U.S.--I know I will--the weather is looking beautiful!!!
