Should you have (single sided) or (double sided 3 layers)?
Single sided flag sample:
The wording on a single sided flag will read in reverse on the back side. This flag take little wind to move it and is the most common way for custom flags.
Double Sided 3 layer flag sample:
As you can see the wording on a 3 layer flag will read correct on the back side. This flag will take a lot wind to move it as it is very heavy, the flag is made from 2 pieces of flag material are sewn together and a middle block out is add to stop the see through,
