You need to really think about what it looks like 60 yards away, I would suggest it takes 4-6 months to come up with a design that you are happy with, even if you think your first design is great chances are a month later you won't. That's not to say your final design will be loved by everyone, because it won't. Think of your target market (i.e. what type of cricketer?) and don't rush it. Also, mock up plenty of prototypes even if its just on plain A4 front your inkjet to start with.
