I thought I'd better find the other flowers to see exactly what I had. On the bottom left are the ones that have the petals all the same colour. The right photo is of all the hexagon flowers I have made, some with different coloured petals.
As all the centres are the same colour, I think I should be able to combine them all without them looking out of place. First, I need to decide what I am going to do with them, I can't remember why I started them, apart from the fact, I enjoy it, lol.
