Looking again at the heart that Joanie pointed me too I decided that it needed an 'outside'!!! It took a few tries but in the end I settled on the 'outsides' below.
I've already started to put this together as a webpage pattern but I've also been playing with it to see what else I can 'turn it into'!!! You'll have to wait a day or two to see 'what happens next' as I've been busy doing other things was well.
These look quite good in one colour but now I'm wondering about using two colours!!! As soon as I've decided on one thing - another idea pops into my head!!!
