Describing characters at once or throughout?
Ok this is just a quick one and probably something that is down to preference, but I am having trouble describing my characters at the start of my book.
Basically in chapter 1, 4 new characters are introduced, and I am not sure if I should take the time to describe the characters from their hair to their skin and clothes, or, whether to just drop details of them with each appearance.
If anyone has any tips or advice on this it would be very useful. I don't want to bore the reader with details.
