The Irish tri-color was first designed by French women and presented to the Young Irelanders during the rebellion of 1848. It's first serious use was in 1916 during the Easter Rebellion. It became the national flag of the Republic of Eire in 1919.
The flag is 3'x5' and made from a premium 100 denier polyester. It has a white header with two grommets. There are four rows of stitches on the fly and two rows on the top, bottom, and header side. The image is screen printed and appears on both sides. Writing will be reversed on the back.
3'x5' flags are 3 feet x 5 feet, 36 inches by 60 inches, 91 cm by 152 cm, 1 yard by 1.7 yards. This is the most common size flag you see hanging on porches, small flag poles, hanging at festivals, and inside of bars and restaurants.
