You can make a metal calla lily by shaping sheet metal into its signature trumpet-like form and attaching it to a sturdy stem.
It’s a rewarding project that blends artistry with basic metalworking skills.
Whether you’re a beginner or a seasoned crafter, making a metal calla lily is totally doable with the right tools and a bit of patience.
In this post, we’ll walk you through the entire process of how to make a metal calla lily, from choosing materials to adding the final polish.
Let’s dive into this fun and creative DIY project together.
How to Make a Metal Calla Lily: The Basics
When you learn how to make a metal calla lily, the first step is understanding the flower’s simple yet elegant geometry.
A calla lily has a curved, flaring spathe that wraps around a central spadix, and replicating this in metal requires careful cutting and forming.
To make a metal calla lily, you’ll need a few essential materials and tools before you start shaping.
Here’s what you’ll need to gather for this metal calla lily project.
1. Choose Your Metal Sheet
The most common choice for a metal calla lily is copper, brass, or aluminum.
Copper is soft and easy to shape, making it ideal for beginners learning how to make a metal calla lily for the first time.
Brass offers a bright golden look that mimics the flower beautifully, while aluminum is lightweight and inexpensive.
For a more durable outdoor piece, you can also use stainless steel, though it’s harder to work with.
A 24-gauge sheet is perfect because it’s thick enough to hold its shape but thin enough to cut and bend by hand.
2. Gather Essential Tools
To make a metal calla lily, you’ll need metal snips or a jeweler’s saw for cutting.
You’ll also want a ball-peen hammer, a steel dolly or anvil, and a pair of round-nose pliers for forming the curves.
A bench block and a center punch will help you mark and shape the metal accurately.
Don’t forget safety gear like gloves and safety glasses, as metal edges are sharp.
Finally, have some fine-grit sandpaper or a metal file on hand to smooth any rough edges.
3. Cut the Petal Shape
Start by drawing a petal template on paper that’s about 6 inches long and 3 inches wide at the top.
Transfer this pattern onto your metal sheet using a permanent marker or scribe.
Carefully cut out the petal shape with your metal snips, following the lines as closely as possible.
Take your time with this step, as a clean cut makes the rest of the process easier.
Once cut, file or sand the edges to remove any burrs so they don’t snag your hands or gloves.
Shaping the Metal Calla Lily Spathe
Now that your petal is cut, it’s time to give it that iconic calla lily curl.
This is where the magic happens in how to make a metal calla lily look real and elegant.
The spathe needs to wrap around the spadix while flaring outward at the top.
Here’s how to shape your metal calla lily to perfection.
1. Anneal the Metal for Flexibility
Annealing softens the metal and makes it easier to bend without cracking.
For copper or brass, heat the petal with a torch until it glows a dull red, then quench it in water.
Aluminum doesn’t need annealing and can be shaped directly.
Once annealed, the metal becomes very pliable, which is crucial for forming the delicate curves of a metal calla lily.
Let the metal cool completely before handling it further.
2. Form the Curved Funnel
Place the petal on your steel dolly and use a ball-peen hammer to gently curve the metal.
Start hammering from the bottom center and work outward toward the edges.
This creates a shallow bowl shape, which is the beginning of the calla’s trumpet.
Then, roll the top edges outward using your round-nose pliers to give the flared lip.
Keep checking your shape against a reference image of a real calla lily as you go.
3. Overlap and Join the Sides
To make a metal calla lily that holds its form, you’ll need to overlap the straight side edges of the petal.
Bring the two edges together so they wrap around an imaginary center, creating a cone.
Overlap them by about half an inch and secure them temporarily with binder clips.
Then, solder the seam using a suitable solder and flux, or use heavy-duty epoxy for a no-heat option.
Allow the join to dry completely before moving on.
Making the Stem and Spadix
No metal calla lily is complete without its central spadix and a long stem.
The spadix is the finger-like structure inside the flower, and the stem provides height and support.
Here’s how to craft these two essential parts of your metal calla lily.
1. Create the Spadix
The spadix is typically a thin rod that extends from the stem up through the flower’s center.
Use a piece of 12-gauge copper wire or a brass rod, around 4 to 5 inches long.
Round one end with a file to soften the tip, giving it a more realistic look.
You can also texture the spadix by tapping it lightly with a hammer to mimic the bumpy surface of a real calla lily.
Slide the spadix into the center of your formed spathe, ensuring it peeks out slightly above the top.
2. Attach the Stem
For the stem, use a sturdy metal rod like stainless steel or heavy-gauge wire, about 12 to 18 inches long.
Bend the top of the stem into a small loop to help secure the spadix and spathe.
Apply a generous amount of epoxy to the loop and insert the spadix’s base into it.
Then, slide the bottom of your spathe up over the stem and seat it firmly against the flower body.
Hold everything in place with tape or a clamp until the adhesive sets.
3. Reinforce the Connection
To ensure your metal calla lily lasts, reinforce the joint between the spathe and stem.
You can solder the stem to the inside of the spathe if you’re comfortable with a torch.
Alternatively, wrap fine wire around the base of the spathe and stem several times.
This hidden wire adds serious strength and keeps the flower from wobbling.
Finishing and Polishing Your Metal Calla Lily
Now that the structure is complete, it’s time to make your metal calla lily shine.
The finishing steps protect the metal and enhance its beauty, so don’t skip them.
A well-finished piece looks like it came from a professional studio.
1. Smooth All Surfaces
Go over the entire metal calla lily with fine-grit sandpaper (400 to 600 grit) to remove tool marks.
Pay special attention to the hammered areas and the seam where you joined the sides.
For intricate spots, use a small file to reach into tight curves.
The goal is a smooth, uniform surface that will reflect light nicely.
2. Apply a Protective Coating
Bare metal can tarnish over time, especially copper and brass.
Apply a clear lacquer or a metal wax to your finished metal calla lily to prevent oxidation.
If you prefer a patina look, apply a liver of sulfur solution to darken the metal, then buff highlights.
For aluminum, a simple automotive wax works great to keep it bright.
Let the coating dry thoroughly before handling.
3. Add a Final Buff
Use a soft cloth and a metal polish compound to give your metal calla lily a brilliant shine.
Buff in small circular motions until the surface gleams and feels smooth.
For a matte finish, skip the polish and just leave the satin texture from the sanding.
Finally, inspect your flower for any sharp spots and file them down one last time.
