Congratulations on gaining your PPL. It's a great achievement and one to be coveted.
Keep in mind the following though. Some of us wear varying numbers of bars for our jobs (three for me). The aeroplane I fly for fun requires me to wear a knackered old RAF grow-bag to keep to keep the oil off (and stop me burning if it all goes horribly wrong), which is badgeless. There are a number of people I know who are infinitely better qualified than I, who turn up at the club looking infinitely more worn than I (most of whom wear four bars for a living and I defy you to pick the out in them flying club).
One in particular, I've seen in T-shirt, Bermuda shorts and a very suspect hat.

(He used to instruct on Hawks and has been kind enough to teach me a thing or ten, so he's forgiven - apart from the hat)
If I could be so bold, you don't need bars unless you're earning a living and your passengers expect to see them. The bit of paper and the fact you can fly an aeroplane ought to suffice, 'cos that's the whole point.
Isn't it?
PS: If you're going to fly round the world a few times (a la Polly Vacher), four bars open a few doors in Africa, in which case we'll let you off.
