Before you begin: choosing and cleaning your shells
Scallop shells work especially well for this craft because their fan shape creates naturally curved petals. New Zealand scallop shells can be quite large, which makes them ideal for creating statement flowers.
If you can’t find scallop shells, try using large pipi, clam, cockle or oyster shells. Look for four shells that are roughly the same size and shape so your finished flower feels balanced.
Only collect empty shells and check whether collecting is permitted at your beach. Never remove a shell containing a living animal.
Before you start crafting, rinse the shells to remove sand and salt. Gently scrub away any dirt with warm, soapy water, then leave them to dry completely. Hot glue and paint won’t adhere properly to damp or dusty shells.
Don’t worry if your shells have small chips or slightly different markings. Those imperfections are part of what makes each shell flower unique.
Materials you’ll need
To make one shell flower, you will need:
- Four clean, dry scallop shells
- A hot glue gun
- Plenty of glue sticks
- A length of medium-weight fencing wire
- Spray paint in one or two colours
- High-gloss black paint for the stem and flower centre
- Half an apple or half a polystyrene ball
- Pliers or wire cutters
- A smooth ceramic tile
- A small amount of baby oil
- A spatula or blunt scraper
- Protective gloves and safety glasses
- A drop cloth or cardboard to protect your painting area
Optional materials:
- White spray primer for dark shells
- Outdoor UV-resistant clear coat
- Acrylic craft paint if spray paint isn’t suitable
- A small wall hook if you want to hang the flower instead of adding a stem
How to make shell flowers
Step 1: Prepare the wire and mould
Cut a length of fencing wire to suit the vase or container you plan to use. It’s better to leave the stem slightly too long at first because you can always trim it later.
Press one end of the wire through the centre of your half apple or polystyrene ball. The apple acts as a temporary mould, helping support the curved shells while you arrange and glue them.
Leave a short section of wire protruding through the rounded side of the mould. The longer section will eventually become the flower’s stem.
Step 2: Arrange and glue the shells
Place your four scallop shells around the mould with their narrow ends meeting in the centre. Arrange them so they resemble the open petals of a flower.
Take a moment to adjust the position of each shell before adding any glue. The edges don’t need to line up perfectly, but the shells should touch at the base and feel reasonably balanced.
Using plenty of hot glue, join the shells together where their narrow ends meet. Work on one shell at a time and hold it in place briefly while the glue begins to set.
Hot glue can cause serious burns, so an adult should handle this part or closely supervise older children.
Once all four shells are connected, leave the flower on the mould for at least five minutes. The glue should feel firm before you move to the next step.
Step 3: Secure the wire stem
Carefully remove the apple or polystyrene mould from the flower.
Using your pliers, trim the short section of wire inside the flower so approximately one centimetre remains. The longer section on the other side will become the stem.
Apply a generous amount of hot glue around the short piece of wire and the centre where the four shells meet. This extra glue helps secure the stem and strengthens the entire flower.
Rub a thin layer of baby oil onto a smooth ceramic tile. The oil stops the hot glue from permanently sticking to the tile.
Quickly turn the flower upside down and rest the glued centre against the oiled tile. Leave it undisturbed for another five minutes, or until the glue has completely hardened.
Carefully lift the flower from the tile using a spatula or blunt scraper. Don’t pull it up by the stem, as this can weaken the join.
Step 4: Apply the base colour
Now it’s time to paint your shell flower.
Set up outside in a well-ventilated area and protect the surrounding surface with cardboard or a drop cloth. Follow all safety and ventilation instructions on the spray-paint label.
If your shells are very dark or heavily marked, apply a thin coat of white primer first. This will help brighter colours look cleaner and more vibrant.
Once the primer is dry, spray the entire flower with your chosen base colour. Apply several light coats instead of one heavy coat to reduce drips and prevent paint from collecting in the shell ridges.
Allow each coat to dry according to the instructions on the paint can.
Step 5: Add a second colour
For an ombré effect, apply a second colour to the inside of the flower, concentrating the paint around the centre and allowing it to fade towards the edges.
Two shades of the same colour can create a soft, natural look. For something bolder, try combinations such as:
- Turquoise and deep blue
- Coral and soft pink
- Lime green and teal
- Purple and magenta
- White and pale blue
You can also copy the colours of a favourite flower or choose shades that match the room where you plan to display it.
If you’re using metallic spray paint, apply it on a warm, dry day. Cool or damp weather can affect the finish and make metallic paint appear dull.
Step 6: Paint the stem and seal the flower
Once the shell paint is completely dry, paint the wire stem and raised flower centre with high-gloss black paint. The dark finish creates contrast and makes the colours stand out.
If your flower will be displayed indoors, you can stop here.
For flowers displayed outside or near strong sunlight, finish with a UV-resistant clear coat. Apply it outdoors according to the manufacturer’s instructions and allow it to cure completely before bringing the flower inside.
A protective coating can help preserve the colour, but these handmade flowers will last longer in a sheltered area than somewhere exposed to constant rain or harsh weather.
Troubleshooting common shell-flower problems
The shells keep moving while I glue them
Arrange all four shells on the apple or polystyrene mould before you begin gluing. Add one shell at a time and hold it in position until the glue starts to set.
Having two glue guns heating at the same time can also help because this project uses more glue than you might expect.
The stem feels loose
Add more hot glue around the short section of wire inside the flower. Let it harden against the oiled tile before testing the stem again.
If the stem comes loose later, it can usually be glued back into place.
The flower looks uneven
Natural shells are rarely identical. Rotate and rearrange them before gluing until you find the most balanced combination.
A slightly uneven flower can still look beautiful, especially when displayed alongside several others.
The paint is dripping
You’re probably applying too much paint at once. Use several light coats and let each coat dry before adding another.
Keep the spray can moving rather than aiming continuously at one area.
The original shell markings show through
Apply a white primer before adding your main colour. This is particularly helpful when working with dark, stained or strongly patterned shells.
The hot glue is too visible
Visible glue can usually be disguised with the base coat. If you have a particularly large lump, carefully trim it once it is completely cold—but avoid cutting into the join that holds the flower together.
Shell-flower Design Ideas
Once you’ve made your first shell flower, try experimenting with different finishes and displays.
Create a full shell-flower bouquet
Make five or seven flowers in complementary colours and vary the stem lengths. Arrange them in a tall, narrow vase to help support the wire stems.
Make natural, unpainted flowers
Leave the shells in their natural colours and paint only the stem and centre. A clear protective finish can help bring out their original texture and markings.
Add a metallic finish
Gold, silver, copper or pearl paint can create a more decorative look. Metallic flowers can work particularly well as table decorations or handmade gifts.
Turn them into wall art
Leave off the wire stem and glue a suitable picture hook to the back. Make several flowers in different sizes and arrange them together on a wall.
Always choose a hook and adhesive suitable for the flower’s weight.
Create flowers with different shells
Try different shell shapes to create different effects. Rounder shells may produce compact flowers, while long or narrow shells can create more dramatic petals.
You could even combine shell types within the same flower, although it may take some experimenting to find an arrangement that sits securely.
How to care for shell flowers
Shell flowers displayed inside need very little maintenance. Dust them gently with a soft cloth, feather duster or clean paintbrush.
Avoid holding the flower by a single shell when moving it. Lift it by the stem close to the flower head, or support the entire flower with your hand.
Keep indoor flowers away from areas where they are likely to be knocked over. Although scallop shells are reasonably sturdy, their edges can chip if dropped.
If the flower is displayed outside, check it occasionally for faded paint, loose glue or rust on the wire. A fresh clear coat can help extend its life.
Frequently asked questions
What shells are best for making shell flowers?
Scallop shells work particularly well because their fan shape resembles flower petals. Pipi, clam, cockle and small oyster shells can also be used, although the finished shape will vary.
Choose shells that are similar in size and have solid, unbroken bases. The bases need to be strong enough to hold the hot glue.
How many shells do I need for one flower?
This project uses four scallop shells for each flower. You can experiment with more or fewer shells, but four creates a simple open flower and is relatively easy to assemble.
How do you clean shells before crafting with them?
Rinse away loose sand and gently scrub the shells in warm, soapy water. Rinse them again and allow them to dry completely before applying hot glue, primer or paint.
Can I make shell flowers without spray paint?
Yes. Acrylic craft paint can be used if spray paint isn’t suitable, although brush marks may be more visible.
Apply a suitable primer first and build the colour with several thin coats. Allow each coat to dry before adding the next.
Can shell flowers be displayed outside?
Yes, but they will last longer in a sheltered outdoor area. Apply an outdoor UV-resistant clear coat after the paint has dried to help protect the colour.
Keep in mind that prolonged rain, strong sunlight and high heat may eventually weaken the paint or glue.
Is this shell craft safe for children?
Because the project uses a hot glue gun, wire cutters and spray paint, it is best suited to teens aged 12+ with close adult supervision.
Adults should handle the spray painting, sharp wire and any steps involving large amounts of hot glue.
What can I use instead of an apple?
Half a polystyrene ball can be used as a reusable mould. Choose one that creates a comfortable curve for your shells and keep the hot glue away from exposed areas of polystyrene.
Why use baby oil on the tile?
The baby oil creates a light barrier between the hot glue and the tile. This makes it easier to lift the hardened glue away without damaging the flower.
