Unique Fall Pumpkin Sheet Metal Art

Did you know you can make ordinary tin look like oxidized copper? I had some fun with an old picture frame, burlap, and a sheet of tin to create unique fall pumpkin sheet metal art with an aged copper patina for our fireplace mantel. With this fun paint technique, you can watch the metal oxidize before your very eyes and now I want to patina all the things.

Unique Burlap and Oxidized Copper Fall Pumpkin Art


With the chilly days of Autumn upon us, my thoughts go to decorating our home for the season. Each year I like to challenge myself by creating interesting Fall decor. I had so much fun with this copper oxidization process that I also used it on my outdoor pumpkin topiaries.

Do I have to make it with tin?

Absolutely not! You could definitely make this Fall pumpkin art with thin balsa wood or as one reader suggested, a disposable aluminum sheet pan from the dollar store.

These are the supplies I used to make it, with the exception of the chalk paint that I had intended to use to paint the picture frame but changed my mind.

Instructions for making oxidized tin pumpkin art


Paint an old picture frame

Too lazy to head to the thrift store to find a suitable picture frame, I rummaged through our storage room and found Mr. Frugalista's college diploma tucked away in a plastic bin. I figured if he's got it hidden away rather than hanging on a wall, then the picture frame and mat must be free for the picking.

Because the wood frame is stained red, it is almost guaranteed that the tannins in the wood will bleed through the paint. To remedy that I applied a coat of shellac that I had on hand to seal (prime) the wood. Any stain-blocking primer or sealer will work.

I painted the frame with copper primer included in the metal effects kit we'll be using later. After the last coat of paint cured for a couple of hours, I rubbed dark wax over the frame with a lint-free rag to give it an aged patina.

Cover the picture frame backing with burlap

I lined the cardboard backing of the picture frame with burlap leftover from a table runner I used to make DIY burlap pumpkins. Wrap the burlap around the cardboard and secure with dabs of hot glue.

How to make sheet metal pumpkin art

Like I mentioned earlier, you don't have to make this pumpkin art with sheet metal. The steps are the same whether you use tin or balsa wood, cut with a retractable utility knife.

Caution:

If you're using sheet metal or tin like I did, it is very important to use caution during this step because the metal is sharp. Protective safety gloves for metal and goggles are a must!

I created a graphic in a Word document with pumpkin clip art and changed the color to grayscale so it would print like a coloring book page. If you click on the graphic below, I've included a Free unwatermarked printable for you to use.

Next, I traced the graphic with carbon paper onto sheet metal. You can find sheet metal in multiple sizes at your local home improvement store usually in the heating & cooling aisle where they sell furnace ducting.

For more detailed information on how to transfer the image visit my Image Transfer Technique With Graphite Paper tutorial.

Carefully cut the pumpkin graphic with tin snips and make sure to wear safety gloves for sheet metal and protective goggles for this step.

Again carefully, dull the edges of the sheet metal with an 80-grit sanding sponge on both sides of the edges OR you could get all fancy and use a handy metal deburring tool.

Green oxidization process on the sheet metal pumpkin art

Once the tin was safer to work with I painted it with two coats of Modern Masters Metal Effects Copper Primer, waiting thirty minutes between coats.

Next, I painted one coat of Modern Masters Metal Effects Copper Paint (my apologies for the blurry photo below) and let it dry two hours before moving onto the next step.

While the second coat of copper paint was wet, I sprayed Modern Masters Green Patina Aging Solution on the leaf portion ONLY. You can see the oxidization process starting to work in the photo above.

While the oxidization process was happening I dabbed the leaf with a scrunched rag so more of the copper would show through the weathered patina.

After the tin dried, I used a cotton swab and blackened bronze metallic surfacer to add some detail to the pumpkin. I outlined around the leaf, added ribs, and painted the pumpkin stem (pictured above).

Once everything dried I attached the tin pumpkin to the burlap backing on the picture frame with dabs of hot glue.

Add tendrils to the tin pumpkin

For the tendrils, I used the printed pumpkin graphic as my guide and simply hot glued a strand of green jute twine from the stem to the leaf.

Add painted wooden letters

Paint 1 1/2 inch wood letters with the same copper primer used on the pumpkin. Once the paint is dry, dab blackened bronze metallic surfacer with a lint-free rag over the painted letters to add depth.

Before attaching the painted letters to the burlap, slip the mat and burlap backing into the painted picture frame. Line the painted wooden letters towards the top and attach them with hot glue.

That's it, we're done!

Fall Pumpkin Copper Art

Mr. Frugalista was not impressed when he got home from work and saw his frameless college diploma on the dining room table. A found frame is a crafter's game!

The DIY pumpkins pictured with my fall pumpkin art can be found here in my painted dollar store pumpkins and ticking fabric pumpkins with cabinet knob stem posts.

Have you ever tried a metal effects kit? If not, besides the oxidized copper patina that I used, they come in weathered bronze or rusted iron patinas.

If you have tried these kits, I would love to hear what you made with them. Or if you have any questions about this project, please leave them in the comment section below or press the Contact Me button at the top of the blog to drop me an email. I love hearing from you!

  3. Hi Marie! I can't wait to get my hands on this product and give it a try. I love how your pumpkin and leaf turned out. I snickered when I thought of the look Mr. Frugalista gave you over his frameless diploma. Hey,a girl's gotta do what a girl's gotta do! Right? I hope you'll share at Homestyle Gathering (if you haven't already)!

  8. Darn it, how I wish we could find Modern Masters here in South Africa. They don't even ship here and I've been dying to play with it for the longest time. Love beautiful patina's on that pumpkin of yours Marie.

    1. That's too bad Michelle but I can relate to your frustration. Oftentimes here in Canada I do not have access to products my fellow blogging friends to the south have, even though we share the same continent. Shipping is pricey between countries.

  9. Marie,
    I fell in love with this picture as soon as I saw it. I adore copper and the copper pumpkin on the burlap with those twine tendrils is spectacular! Yes, that may sound "overdone" but it's spectacular to me. I see one in the works!!! Thought I could use a DT aluminum disposable pan to cut the pumpkin from and paint it copper! Love your work.
