Triangular Pennant Banner (Knitting Pattern)

Celebrate special holiday seasons with a Knitted Triangular Pennant Banner! Continuing my Summer Knit Series and with the 4th of July holiday upon us, my sample is in the colors of our flag with red, white, and blue yarns. I have also added my little Star Shape embellishment.

Get creative with your yarn colors and design to festively celebrate any holiday. A string of triangle flag shapes creates this bunting garland decor that looks great both inside your home and outside by the grill.

This free knitting pattern includes my fun video tutorial that gives you an overview of everything you need to know, so make sure to check it out!

CLOSER LOOK at the Pennant Banner Pattern

Let’s take a close look at our Pennant Banner Pattern, seeing exactly how those knits and yarn over increase stitches are knitted together to make this simple pattern.

Your triangle shape is knitted flat from the bottom up. Increase stitches on the right side of your work creates your isosceles triangle shape. You can easily modify the triangle size by knitting it up until it is the length you desire.

The two sides of your triangle have a pretty, airy eyelet border and the top is finished off by using the Stretchy Bind Off technique. This allows the top of your banner to lie flat without it being bound off too tightly.

When knitting your pennant banner in just one color, it is a reversible pattern making it look great on both sides. However, if you are knitting stripes, it will NOT be reversible and you will have noticeable purl dash lines on the wrong side of your work.

I added a little knitted Star Shape to my center pennant since this is a Patriotic themed banner. Check out my Star Shape knitting pattern and video tutorial to make one, too!



Create your banner by attaching any number of triangles and in any configuration you wish. I connected mine with Ribbon and Yarn. I think Jute Twine would look really cool and rustic, too.

ABOUT BERNAT MAKER OUTDOOR YARN: Since Pennant Banners are great decor for the yard, I am using this Bernat Maker Outdoor Yarn in colors Beach Red, White, and Royal Blue. It’s a great bulky weight yarn and easy to knit up. Its colors do not fade in the sunshine and it is mold resistant, too! I’m excited to yarn bomb with this yarn in the near future, too!
