All the country flag patches offered in Globenir are sized 6.3 x 3.6 cm. They can be either ironed on or embroidered, according to your liking.
Here are the steps for attaching them:
Turn on your ironing machine to its highest heat setting to make sure the patch adheres properly to your fabric.
Place your patch on the marked spot on your fabric, place a thin cloth on top of your patch, and iron for 30 seconds.
Let it cool down for 30 seconds.
Repeat step 2 and 3 if the patch did not stick.
About the Flag "Nigeria flag consists of green and white colors that divide the flag vertically. While the green color on the fluctuating side of the flag symbolizes the agricultural lands and the green nature of the country’s economically backbone, the white color in the center represents peace and unity."
