/*
Poppy tested the old DogLabel and they only lasted a year or so. The outline came off,
and then one of the telephone number digits came off.
So this version uses indentations on BOTH sides, which should make it more durable (but less pretty).

I recommend printing in 3 colours.
I chose Dark Red, Pink, Black, but the pink and red were a bit too see through
and the darkness from the phone number was apparent from the back.
