I then tried putting them into the petals of a flower, the petals are purposely different sizes to accommodate the different number of birthdays in each month.
Which I made yellow
and then more colourful
I like the idea of a flower so I played with some more ideas
which lead to this which is based on a sunflower
the centre is a bit dull so I thought I'd add some lettering
better if the petals are closer together and the centre is more like a sunflower?
This could then be written on with the birthdays
maybe better with a bit of adjustment?
I think actually I prefer my first attempt for its clarity and simplicity
