Many years ago, in my youth, I inherited a very old book full of botanical drawings of flowers. (It's well over 100 years old - I have had it for at least 60 years and it was very old then!) It is one of my treasured possessions. I love it, and always wished I could draw like that. I love flowers, and of course I have made many in sugar over the years.
I am even considering using the techniques I learned from this drawing of the geranium, to try and draw a hydrangea, as it is basically the same shape of blooms, the petals just being in fours rather than fives.
