re: Real flowers on a cake

Hi Roo. The trick is knowing how to wire them properly… I will include a link at the bottom, which might be useful for you.
Choose the freshest flowers, and ones that will keep well.
Don’t prepare too far in advance… I would suggest no more than 24hrs.
Store in a cool place, you may refrigerate as long as it is not too cold.
For the bit cascading down the side, actually start with the flowers that will be at the bottom, and as you add to the trail, tape as you go. Join the trail to the top bouquet when done.
P.S. Make sure your flowers are food grade, free of pests, pesticides and not toxic.
