Chapter One: What Are Yard Letter Signs: The Specs
The letters can be cut as high as 18" and the width will vary depending on the font that you select. Speaking of fonts, we offer three engaging typefaces to choose from:
- Capucine Basic Italic
- Helvetica Neue
- Urbane Rounded Heavy
That was the physical breakdown of the attributes and details for these letter signs. Next we will cover how to use them for your events.
Chapter Two: Using Letter Yard Signs for Events
Many neighborhoods have a tradition of decorating each other's front yards for birthdays, placing pink flamingos in all sorts of places to surprise the birthday person when they return home.
Now, imagine if they added some custom flamingo-pink "Happy Birthday" lettering? The landscape would be complete.
Yard letter signs can be ordered in a prearranged birthday message, in many different themes and color patterns. This manages certain design decisions that may not be easy for everyone. It is like choosing a premade cake instead of designing one yourself. No shame in that.
Chapter Three: Fun Lawn Letter Ideas to Try
We all decorate for birthdays and holidays, but what about events like the first day of school or passing a driver's test? There are many other occasions to be celebrated besides the obvious. Just use your imagination.
You could also display letter signs for getting good grades, or just for fun. Cheer up the people in your life with alphabet-shaped plastic lawn implements. Yard letters can be used like a "just because" card or random flowers on the kitchen table. But in this case, the whole block gets to see it.
Chapter Four: Benefits of Large Letter Signs
The benefits certainly outweigh the risks. Who wouldn't love some colorful yard letters in their grass? These decorations are:
- Easily removable
- Customizable
- Waterproof
- Low maintenance
