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 "In the local Thai language, the flag is known as Thong Trairong, which translates to the Tricolor flag.
The National Flag of Thailand features five horizontal bands of red (top), white, blue (double width), white, and red. The red color symbolizes the nation and the blood of life. The white color represents the religion of Buddhism and the purity of the Buddhist faith. The blue color stands for the monarchy." (source: worldatlas)
