There are several materials to choose from when purchasing a flag. There are many variables that determine a flags quality, durability and price. Materials used for flags are designed for specific use, flying habits and climate. They vary in thickness, weave and weight. The quality of the inks used to dye the material, or for the digital printing process, determine the level of fade resistance and color fastness. The type of thread and methods to stitch the flag and the fly ends determine whether your flag will fray or shred in high winds. The most popular and best waving flag is nylon – USA Flag Co.
