This project uses simple garden trellis or wooden lattice to create a rustic American flag design that can be hung on a porch wall, garden shed, fence, or outdoor entertaining area. The crisscross pattern of the trellis gives it that handmade farmhouse look, and when it’s placed above a row of sunflowers it has that gorgeous summer garden charm that feels perfect for the 4th of July, Memorial Day, Labor Day, or any Americana-style porch display.
It is also a great way to use up an old piece of lattice from the garden. You know the sort — the one leaning behind the shed because “it might come in handy one day.” Well, congratulations, today is that day.
For more simple patriotic display ideas, you could pair this with these patriotic quote blocks on a porch table or make a matching patriotic star block craft for a layered front porch vignette.

What you need
One rectangular piece of wooden garden trellis or lattice
Outdoor craft paint or exterior house paint in red, white, and navy blue
Paintbrushes or foam brushes
Painter’s tape
Pencil
Ruler or measuring tape

A good outdoor acrylic paint, foam brushes, and a clear exterior sealer are worth having on hand for this project. You can usually find inexpensive options through Amazon or your local hardware store, and if you are planning a few summer craft projects, the supplies will definitely get used again.
Instructions
Step 1: Choose Your Trellis
Start with a rectangular piece of wooden trellis or lattice. The size is completely up to you, but a longer horizontal shape works best because it gives the finished piece that flag-style look.
If your trellis is too large, trim it down carefully with a saw. If you are not confident cutting wood yourself, ask your hardware store to cut it for you when you buy it. No shame in outsourcing the noisy bits.
Lightly sand any rough edges or splintery sections. This does not need to be perfect, especially if you like a rustic outdoor look, but you do want to remove anything sharp or flaky before painting.
Step 2: Clean And Prepare The Wood
Wipe the trellis with a dry cloth to remove dust, dirt, and loose bits of old paint.
If you are using recycled trellis from the garden, give it a proper scrub first and let it dry completely. Damp wood and paint are not friends, and rushing this step usually leads to peeling paint later.
Step 3: Mark Out The Flag Design
Lay the trellis flat on a protected work surface.
Using a pencil and ruler, lightly mark a rectangle in the upper left corner for the blue section of the flag. This will be your canton area.
Because trellis has a crisscross pattern, don’t stress about making it mathematically perfect. The handmade charm is part of the look. Aim for a blue section that covers roughly the top left quarter to third of the flag.
Next, mark out horizontal stripe sections across the rest of the trellis. You can use painter’s tape to help keep your red and white areas tidy.
Step 4: Paint The White Base
Paint the entire trellis white first, including the background stripe areas.
This gives you a bright base and helps the red and blue stand out. If your trellis is already white, you may still want to freshen it up with a coat of outdoor white paint.
Let the paint dry completely before moving on.
Step 5: Paint The Blue Section
Paint the upper left canton area navy blue.
Work carefully into the lattice strips and edges. A small brush is helpful for getting into the overlapping sections without making too much of a mess.
Let the blue paint dry before adding the red stripes.
Step 6: Add The Red Stripes
Using your pencil marks or painter’s tape as a guide, paint alternating red stripes across the trellis.
Because the trellis is crisscrossed, the stripes will look broken and woven rather than flat and solid, which is what gives this project its lovely rustic texture.
Let each color dry before touching up the next. If you accidentally paint outside the lines, don’t panic. Once everything is dry, you can touch up with white paint. Outdoor crafts are very forgiving, especially when they are meant to look rustic.
Step 7: Add A Weathered Farmhouse Finish
Once the paint is fully dry, lightly sand a few areas to distress the surface.
Focus on edges, corners, and raised sections of the lattice. This gives the flag a softened, aged look rather than a freshly painted “too perfect” finish.
Wipe away dust with a clean cloth.
Step 8: Seal For Outdoor Use
Brush or spray on a clear outdoor sealer.
This step is especially important if your flag will be exposed to sun, rain, or sprinkler spray. Apply according to the product instructions and allow it to cure fully before hanging.
If your wall gets a lot of weather, two light coats of sealer are better than one heavy gloopy coat. Ask me how I know.
Step 9: Hang The Trellis Flag
Decide where you want to hang your flag. A white brick wall, garden shed, porch wall, or fence all work beautifully.
Use outdoor screws, brackets, or suitable hanging hardware for your wall surface. If hanging on brick, use masonry screws or anchors.
For extra dimension, add small spacers behind the trellis so it sits slightly away from the wall. This creates a nice shadow and makes the lattice pattern stand out.
Step 10: Style With Sunflowers
Plant sunflowers beneath the flag for that bright summer garden look.
If you don’t have time to grow sunflowers from seed, you can use nursery-grown sunflower plants in the garden bed or place potted sunflowers along the base of the wall. Faux sunflowers can also work for a temporary party display, especially if you’re decorating for a barbecue or front porch photo spot.
Add mulch, small yellow flowers, or leafy green plants around the base to make the whole display feel full and intentional.
Tips For Making It Look More Natural
Use slightly muted paint colors rather than super glossy primary shades. A barn red, warm white, and deep navy will look more charming and less like a plastic party decoration.
Don’t make every stripe perfectly crisp. A little dry brushing and distressing helps the piece feel handmade.
If using faux sunflowers, mix different heights and sizes so they don’t all sit in one neat row. Real gardens are wonderfully bossy and uneven, and that is what makes them beautiful.
Mount the trellis flag with a tiny gap behind it so it casts a natural shadow on the wall.
Variations To Try
For a smaller porch version, use a half sheet of trellis and hang it above a potting bench or outdoor console table.
For a cottage garden look, plant it above sunflowers, daisies, black-eyed Susans, or lavender.
For a budget version, check thrift stores, salvage yards, marketplace listings, or your own garden shed for old lattice panels that can be cleaned up and painted.
For a more rustic Americana display, add a small wooden crate, lanterns, terracotta pots, or a simple burlap bow nearby.
Where To Display It
This DIY American flag trellis looks lovely on:
- A white brick wall
- A garden shed
- A backyard fence
- A covered porch
- A patio wall
- A potting bench backdrop
- A party photo wall
- A front porch entryway
It is especially pretty for summer entertaining because it feels festive without being overdone. You can leave it up for the whole season, then tuck it away with your outdoor holiday decorations when the weather turns.
Project Notes
If you plan to hang this outdoors long-term, choose exterior-grade paint and seal it well. Trellis is usually thin wood, so it can weather quickly if left completely unprotected.
You can also make this project using plastic lattice, but wooden trellis gives a warmer, more handmade look and is much easier to distress.
This is one of those projects that looks far more impressive than it actually is. A bit of paint, a bit of patience, and suddenly that old piece of garden lattice has turned into cheerful patriotic outdoor wall decor. And really, isn’t that the best kind of craft project?
