Whether you call it bunting, a pennant banner, or fabric triangle bunting flags, this is one sewing project where you can create festive DIY decorations for holidays, baby showers, birthdays, sports events, and other occasions.

It doesn’t take very long to make one strand of bunting and if you batch the steps in the process, you can quickly make multiple strands at one time.

Flag Templates for Pennant Banners

Bunting isn’t hard to make but having different size flag templates will make it easier for you.

DIY Bunting with Flag Templates

The pennant banners in the image above are made out of red, white, and blue fabric for patriotic porch decor. The flags are double-sided so both sides are finished and look good no matter where you are standing.

Number of Flags and Length of Bias Tape

When you make bunting, you decide on how many pennant flags to sew. You’ll need 2 triangles for every flag so keep that in mind as you cut the fabric.

The double wide bias tape you purchase usually comes in 3 yard lengths and you decide how far apart to place the flags.

On each strand of store-bought bias tape in the above picture, there are 14 flags spaced one inch apart. That left plenty of room to hang the bunting on either end.

The video below will show you how to use the FREE paper templates that you can download from this post to make bunting out of fabric.

How to DIY Bunting with an Acrylic Template

After following the directions in this picture tutorial, you’ll know how to use an acrylic template to cut flags for bunting, sew the flags, and create the bunting.

*Commercial Template

*In the tutorial, I used a commercial template made to be used with a rotary cutter. It is part of a set that was designed to go with a Dear Jane quilt.

The completed banner uses two different fabrics, has 8 pennant flags, and is just under 6 feet long.

Tip: Read all of the steps before you begin.

Gather the Supplies

• cotton or cotton-like fabric – a minimum of 1/4 yard with a width of 44-inches
  • This will make 8 pennants. There are 2 triangles for each pennant.
  • You may need more fabric if you’re going to fussy cut the triangles.
  • Note: I used Cleveland Browns themed fabric for the front and a solid color for the back of the pennants. I purchased 1/4 yard of each fabric.
• extra-wide, double-fold bias tape, 3 yards
• thread
• scissors
• pins
• rotary cutter, mat, and ruler
• sewing clips (optional)
• seam gauge
• marking pen (if you use a paper template)
• a triangle template*

*You don’t need an acrylic template to make bunting. To provide you with options for the flag shape and size (including the same size I used in the tutorial), fill in your name and email below and I will send you 3 flag templates for FREE.

After printing the templates, just cut them out and trace them on a file folder or other thick paper. These thicker templates can then be cut out and used to trace the shapes on your fabric with a marking pen. (See the video linked above for a step-by-step tutorial.

Get Your Sewing Machine Ready

Put a 1/4″ presser foot on your sewing machine. If you don’t have one, you can use an all-purpose presser foot. Just use the edge of the foot as the guide when sewing.

Prepare the Fabric

• Prewash the 100% cotton fabric in warm water and dry in the dryer.
• Press to get the large wrinkles out.

Cut the Bunting Flags

Tip: Read all of the steps before you begin.

Cut the fabric to be the height of the triangle template. This will allow you to make fewer cuts as you cut out the triangles.

Place the triangle template on one end of the fabric strip. Line up the top and bottom of the triangle with the top and bottom of the fabric.

Use the rotary cutter to cut one side of the triangle then the other.

Tip: If you’re using a cardboard template, draw lines on the fabric then use either scissors or a rotary cutter quilting ruler to cut the fabric.

Invert the triangle template, lining up the edges. Cut another triangle.

Tip: If you are fussy cutting, the edges of the cuts may not line up with the template as you cut more triangles.

Keep going until you have all the triangles you need.

Note: If the fabric has a pattern, pay attention to its direction as you cut triangles. Using the cutting method above, the pattern may be upside down. When constructing the bunting, these triangles could all go on one side and be the back.

Prepare the Flags

With right sides facing each other, pin two triangles together. Make sure the edges are lined up.

Optional step: Before sewing, use the measuring gauge to mark the place where you will pivot the needle at the point. It will be centered at the triangle point 1/4-inch from the edge of the fabric.

Sew the Flags

Start sewing at the top of the triangle. You’ll use a 1/4-inch seam allowance. Sew down one long side, pivot at the point, and sew up the other long side. Leave the top of the triangle open.

Trim off material at the point. Be careful not to cut the stitches.

Turn the triangle right side out. Carefully push out the point with the closed end of a pair of scissors or a specialty tool if you have one. Use a pin to carefully pick at the point from the outside to make it sharp.

Press the pennant so it lays flat and the edges are crisp.

Attach Bunting Flags to Bias Tape

Open the package of extra-wide, double-fold bias tape and press out the creases.

Leave a tail of bias tape at least 12-inches long. Open the bias tape and place the top of one pennant right against the fold. Pin or clip it in place.

Space the pennants out evenly. I left 1-inch between mine.

Measure another 12-inch tail after all pennants have been attached. Cut off excess bias tape.

One side of the bias tape is slightly longer than the other side. Sew with the shorter side on top. Sew the bias tape close to the edge.

That’s it. You’re done!

Bunting as Gifts

Pennant banners make great gifts. They are simple to make and easy to customize through fabric selection.

Who in your life would be thrilled to hang a pennant banner either as a room accessory or an as-needed decoration to celebrate sports games or party event?

Bunting makes great gifts for baby showers, too.

Personalize the bunting with the baby’s name. Check out the applique letter templates I created just for this purpose – Sew Many Letters.

Cleaning Tips

If the fabric was preshrunk, you can clean it by washing it on delicate and then hanging it up to dry.

Consider using a lingerie bag when washing and drying in a machine. The lingerie bag should be large enough that there is room for the pennant banner to move around.

Press out any wrinkles.
