A quick sample edge on half of 4 blocks....to see if it works
IDEA1: Pick one colour from each block of 4 and do s SC row all around the block then join with the same cream?
IDEA2: Join all 9 blocks with the same cream first then add a border of SC stripes, with cream between?
IDEA3 Pick only one colour and do the narrow SC round on all the blocks and the border in the same way using only one colour and the cream?
IDEA 4: Use a contrast colour to the flower colours on each block and then join with cream and a border of SC in all the chosen colours wih cream between?
l'm still not sure
IDEA 1,2,3or 4?
